You could, totally, for non-professional use.
HDR is more than just a wide gamut. There's peak luminance, intraframe contrast, tone-mapping etc.
 

BT.2020 for now (and for the near future) is only used as a container, the actual encoded gamut for HDR is P3 D65.

Dell UP2718Q is a proper HDR monitor with FALD, about $1500.
The new Atomos Shogun 7 also uses FALD and costs $1500.

Exmor RS is BSI and stacked.
Faster readout because logic layer is now a whole dedicated layer (stacked), so more room for a substantial amount of low powered ADC working concurrently. Also DRAM can be stacked on an additional layer, but DRAM is not usable for video mode. 

Sony Semicon's Exmor RS line has now fully matured and will come in various sensor sizes - all 8K capable.
One of the first to make the debut is a 45MP Micro 4/3 (MFT) sensor with 2.24um pixel size.

Yes it will have 8K because it will use the 50MP sensor on A1.
It won't have A1 level AF but it will shoot 8K UHD 60P with 1:1 readout (slight crop).

There will be several major firmware updates for FX3 to differentiate it from A7S III. They are not made available at launch partly because Sony do not intend to cut into A7S III sales too much.

Other than polarisation filter, all filter effects can be precisely emulated digitally in post. This allows for much greater and finessed control and guarantees glare-free.

A1 readout modes:
8K up to 30P: Over-sampled from 8640 x 4860 full width readout. 17ms rolling shutter. 1/57s readout speed.
FF 4K up to 60P: 2 x 2 pixel-binned from full width to 4320 x 2430, then over-sampled to 3840 x 2160. 9ms rolling shutter. 1/114s readout speed.
4K 120P: 2 x 2 pixel-binned from 7680 x 4320 window (1.12x crop) to 3840 x 2160. 8ms rolling shutter. 1/124s readout speed.
S35 crop 4K up to 60P: Over-sampled from 5760 x 3240 window (1.5x crop) to 3840 x 2160. 11ms rolling shutter. 1/90s readout speed.
 

Alexa's rolling shutter performance isn't that impressive.
Alexa XT: 8ms in 16:9/4:3 2880 sensor mode, 13ms in open gate sensor mode.
Alexa LF:  14ms open gate mode.
Alexa 65: 15.6ms open gate mode.

Best A1 review IMO:

It uses IMX477, a BSI & stacked 1/2.3" 12MP sensor.
It's capable of full 12MP readout at 60fps with 10bit ADC, and 40fps with 12bit ADC.

Still can't disable edge enhancement and noise reduction on iPhones.
