It's exactly what the NX1 needs, tones down the greens and over-sharpening.
The great thing is, with the hack and Gamma DR you can stick it at ISO 800 and rarely need to go higher, you just push the exposure in post.
Really cleans up the image and stops the overzealous in-camera noise reduction from muddying it up. Never shoot at ISO 6400 on the NX1, always at 800 and boost it in post!

You're welcome!
Video is tricky and colour and colour science is especially tricky because it's a very very deep subject.  
The main levels I see in colour are:
Use camera on full-auto in standard colour profile, don't adjust in post Dial in a profile to get the results you want in-camera, maybe using a grey-card and maybe not Shoot log using a grey-card and grade in post using LUTs and basic adjustments Grade manually without relying on LUTs to do the work Professional colourists I also hang out on liftgammagain.com which is aimed at professional colourists and in many ways the gap in skill level and knowledge between 3 and 5 (or even 4 and 5) is larger than the gap between 1 and 3.  If you're curious to have a tiny taste of what a professional colourist skill level might be like, check out Juan Melara on YT.  It's a fundamentally different kind of skill level. Here's a couple of videos to get you started:
In talking to the professional colourists I've come to understand that the world of Hollywood and the real pros has basically no overlap with the YT world - if all you know is YT then you've never seen a glimpse of how that other world works, with the only exception I know of being Juan Melara.  I'm happy to point you to other resources where pros hang out if you're curious.
In this sense I appreciate that you're torn between people that haven't got a clue how little they know and probably complain about anything resembling work, and those with more knowledge criticising you for not catering to a more informed audience.

Updated the instructions in the first post, so they're more detailed and cover the preparation steps / nx-on-wake.

The original creator's instructions are in the Readme.txt file as part of the download (links below), all credit goes to the hack dev. You must read this before installation. However I thought I might summarise how to get started here in a sticky post to save searching for help (if you need it) in the long threads.
PREPARE CAMERA
1. Ensure fully charged battery
2. In the main menu, ensure Auto Display off = 5 minutes and Power Save = 10 minutes
3. In the main menu, ensure Touch Operation = on
4. Ensure firmware is version 1.41 for the NX1 (you can view this in the main menu under the option Device Information). If older, update firmware according to Samsung's instructions online or via Wifi in the camera menus.
5. Format a memory card in-camera
6. Turn off bluetooth and wifi, set mode dial to M
PREPARE THE NX-ON-WAKE PATCH
1. From the following link download nx-on-wake.zip https://github.com/ottokiksmaler/nx500_nx1_modding/blob/master/nx-on-wake/nx-on-wake.zip
2. Extract all files in nx-on-wake.zip to the ROOT directory of your SD card.
3. Insert the SD card into the camera, turn on the camera and wait
4. A touch screen menu appears to enter a "Magic Number". This is in the Readme.txt, to ensure you have read it. Please look at that document carefully for the 6 digits. I found "357669" but check to see if different.
5. Message "Thanks, preparing the ground" will appear and the display will go blank momentarily. Green light begins to flash...
WAIT AT LEAST 5 MINUTES
6. Leaving the camera powered on, pull the battery out and wait 10 seconds, then put the battery back in.
WAIT AT LEAST 4 MINUTES
7. Turn off the camera using the power switch.
8. Pull the battery, wait 5 seconds and put the battery back in. Turn on the camera.
9. Look at the green LED, you will see it blink 4 times (one long and three short blinks), to confirm everything went ok.
10. Turn off the camera and remove the SD card.
INSTALL THE MAIN HACK
1. Download nx-patch.zip from https://github.com/ottokiksmaler/nx500_nx1_modding/tree/master/video-bitrate-mods/nx-patch
2. Delete the all the nx-wake related files and folders from the SD card
3. Extract the nx-patch zip and place everything in the root directory of your SD card
4. Insert card into camera, turn on the camera and wait for the 'Please wait, installing...' message and for it to do its thing
5. Hack should now be activated, turn off/on camera and you can enter the hack menus by rapidly double-pressing the LCD illumination button on the NX1
6. In the hack menus (double-press LCD illumination button), you can select bitrates, and change Pro1 from 80 to an even higher value like 160
7. Press the "Make persistent" option to save any modifications so they remain on the camera at next cold boot
8. Please make sure you have the fastest possible SD card for Pro bitrate 4K recording (80Mbit to 160Mbit). Happy shooting!

Hello! I recently made a tutorial in covering how to make film halation and grain in Resolve!
I used two methods. One using the GHAlex LUTs for the GH5 and another way using Color Space Transform. 
This is my first ever video tutorial so I apologize if it's a little boring and long.
Tutorial - https://www.youtube.com/watch?v=20epDbE9Adc
Here's some examples using this method - https://www.youtube.com/watch?v=luaGcO-nzd8

If you like this, feel free to download the Power Grades I've provided on my website and experiment with them.
Thanks!
 

Arourke - just wanted to say thanks for the LUTs! I've just recently started playing with them and am getting great results with that 1DX LUT. My Gamma DR settings are slightly different than yours but it seems to work very well with it.

Here are the ones for 16-235. These are all (beta) versions. I tested it out on some older footage and seemed to work good. The brightness isn't standardized/corrected so I would recommend bumping them up the shadows and lowering the highlights.

Glad you liked it! I plan on touching up the lut with the knowledge I have gained from making more luts since, but I am also pretty happy with it as is. I have a few more coming soon.
I have made all of them with the base correction with the Color Checker, but it is not necessary to use them. I have designed them to not require one, but may end up posting luts that you could stack after applying a color match/correction base per each shot for improved accuracy (if you have a color checker and use it for each shot). Just use the suggested in camera settings in combination with the lut. On a side note these are all made for 0-255 which premiere clips to 16-235 on h265 files. I just use RMMC to convert to prores.
I have been focusing on creating a main group (probably 10) and will limit posting of alpha/beta test versions of them for now. I do think an individual thread would make sense. Partially due to the amount of photo/video needed to properly present what each lut does, but to also not crowd/bury other settings. Organization also helps!
I am working on this. I have a backlog of video shot with these settings (so I have some motivation to rework the main accuracy one). The colors/saturation/luminence do not uniformly scale between in camera settings, so it does require me to remake the lut(s) from scratch. Fortunately I have gotten better after creating a few.

arourke! that lut is just AMAZING. I used your settings but didn't touch the MBL (except one high contrast scene) just amazing.
Smart Range+ ON and Exposed for Highlights ISO 100. My best footage ever. :-)
Converted to Prores SQ with RockyMountain, then applied your lut. no other changes. perfect!
 

I was curious about the saturation, it should be less neon with the suggested settings I listed. All of the settings have a "beta" tag on the names currently. I plan on updating the settings to work for other in camera settings (Normal Gamma, Gamma C, etc), once they are more finalized. Just a quick preview of the ungraded video, accuracy/general lut, canon/1dx lut, and classic chrome lut. I am pretty happy with the general lut and 1dx. The classic chrome works well for landscape/city scapes, but I still have some luminance issues with skin tone to adjust.

Looks pretty good. There is a slight green cast to the highlights (neck area) in the second clip. It might just be down to how each camera handles color balance/temp. The purple looks more saturated in the second clip. I doubt viewers would really notice either that much.

Looks nice! I actually lived in Texas until last year. Glad to see the lut/settings working out for someone else. I have uploaded another LUT for the same settings based off Canon's 1DX Camera Standard profile and applied it to your original as a reference.

I plan on working on some Fuji ones next (classic chrome, astia). I have some alexa and actual film ones I am playing with at the moment, but no idea how long they will take.

Just tried this. Original and graded:

Thanks. I am pretty happy with the settings and plan on sharing some videos soon. I have had some good results at night other than a few underexposed auto white balance with mixed sodium/fluorescent (but even those I believe are really down to it being underexposed and bad lighting). I plan on building a separate corrective lut for night uses after more experimenting/testing.

Ttbek Hello, you're right, I also do not want to finish my projects with a white beard, so I have been working on this great project.
Now I can offer two new accessories:
1) lens NXL speed booster,
2) smart adapter.
I do not want to work on the code for communication between the camera and the lens, I have experience with metabones smart adapter, he had a multitude of problems with Sony a7s, it was always in the crash, so I anticipate that it is an experiment already failed in start which will never work well.
I think it's better to work on a separate autofocus independent reporting system that measures the framed object distance, this is possible and we have the technology and economic resources to do so p (the rest will publish some projects).
While waiting I invite you to watch this latest project, very useful for all videomakers.
Thank you, I wait your order for NXL today ;-)

Here is an updated lut for the settings. This was created with the use of Resolve's color match then HSL curves to further match a RAW file of the same scene with a DNG profile created from Xrite's software. It isn't a perfect match, but it is definitely usable as is (and a RAW file has much more latitude).
Color Checker NX1 Settings
Luminance Level 0-255, Master Black Level -5
Gamma DR {Color - 1.00Red, 0.95 Green, 1.00 Blue, Saturation: -3, Sharpness: -10, Contrast: -3, Hue: 0}

Photo/Raw file with a DNG profile applied generated from X-rite's software into lightroom (same scene/settings in camera)

Yeah the Color Match feature isn't perfect, but I still like it as a starting point. I have attached a screenshot of a mask applied to one strip of colors in the chart. I usually then apply a slight Hue vs Hue, and Hue vs Saturation curve then move on to grading. The chart in this specific shot was shot under an overcast day, so green and yellow were pretty vivid in person. 

I plan on doing a comparison between RAW NX1 images with an Xrite dng profile applied verse videos with resolve's color match. Partially for better accuracy and also so that I might be able to imitate how I tweak (and presets) images in Lightroom (depending on how much I can push the files). I am currently not using the bitrate hack, but I would imagine it would help with the video's flexibility to grade further.

The lut (alpha test version) was designed for the following settings:
Color Checker NX1 Settings
Luminance Level 0-255, Master Black Level -5
Gamma DR {Color - 1.00Red, 0.95 Green, 1.00 Blue, Saturation: -3, Sharpness: -10, Contrast: -3, Hue: 0}
The other settings below came close in accuracy, but didn't work as consistently across color temps (so I would not recommend them unless someone else wanted to do further testing with a Xrite Color Checker).
Alt Color Checker Rough Draft (don't use this!)
Luminance Level 0-255, Master Black Level -5
Gamma DR {Color - 1.04Red, 0.93 Green, 1.04 Blue, Saturation: -3, Sharpness: -10, Contrast: -3, Hue: 0}
If you haven't used the Color Match feature in Davinci Resolve before, it does result in an overall desaturated/neutral image once applied (just an accurate starting point). The intent of these settings is to have as minimal of grading applied from in camera video to a color accurate starting point. This would also help with having more latitude to match other cameras. Most of this is to correct the shift/inaccurate deep red/magenta, deep blue, and aqua/teal colors (which in turn help skin tone and in general). At the moment I do not know how beneficial these settings will be without the use of a color checker. Currently I use the color checker to set a custom white balance and then use color match in resolve(the lut I attached was generated off of the color match feature in resolve). The lut is just a (beta test) file for people who do not have a color checker who want to try these settings.

Within Resolve or other programs you can then convert from Rec.709 to Linear or other color spaces after using the settings and lut as a starting point.

I used the 16-50 2/2.8 S lens only (only lens I have for it). I generated a LUT from resolve's Color Match feature (input LUT) if you would like to play with it. Keep in mind this is based of a single example after setting my white balance with the gray card and the listed settings. For a more accurate run and gun setting (when I don't have the color checker with me) I would ideally find the average variation between color temps and in camera white balance.
Gamma C was more accurate than Normal (Gamma DR being the best). I tried out all of the picture wizard settings, but they were pretty all over the place (not that I was expecting much out of Forrest or Retro). A second setting that came oddly close to my listed settings from the last post used all of the same settings except for (color 1.04 Red, 0.93 Green, 1.04 Blue).

I am going to play around with this setting in some non-clinical uses. I like it so far in tandem with resolve's film looks, as long as they are scaled back a little. I do like Ricardo's Settings with Gamma C and the raised black level for more heavily graded uses.
