Here is a quick (unscientific) test of the GX85 vs ZS100 with the Cinelike D profile applied. Maybe somebody with more experience than me can tell me if it's working on the ZS100. It's close enough for me but I'm by no means experienced in this.
GX85 on the left ZS100 on the right. Second half of the video has the Noam Kroll Cinelike D LUT applied.
GX85 (17 1.8): 0,-5,-2,-5
ZS100 (at 41mm): -3,-5,-2,-5
ZS100 showed a little more contrast so I dialled it down to -3 and seems pretty close. I used AWB which may be responsible for the red cast outside on the ZS100.
Settings were 4k30, F4, ISO200 (ISO400 inside) Aperture priority (default exposure)
