hmm... looks off in that pic. 10-bit RGB is the native production colorspace from a technical interview with the studio so it's good you kept 10-bit YUV 4:4:4, but the HK UHD BD metadata levels were way off compared to JP UHD BD such that no display would be able to display it correctly:
https://nyaa.si/view/997137#com-5
JP:
Mastering display luminance : min: 0.0050 cd/m2, max: 1000.0000 cd/m2
Maximum Content Light Level : 777 cd/m2
HK:
Mastering display luminance : min: 0.0000 cd/m2, max: 10000.0000 cd/m2
Maximum Content Light Level : 4996 cd/m2
Maximum VESA HDR certification is DisplayHDR 1000 and only goes up to luminance of 1000 cd/m2 = max that JP BD uses for authoring
What did you use to covert HDR to SDR? I know of avisynth's and ffmpeg's tonemapping filter
@npz: To convert from HDR to SDR, I used the Hable tone mapping over Vapoursynth.
There is [a native version](https://github.com/ifb/vapoursynth-tonemap), but in my case I used a python version of it.
Colors do look faded on my playback system (MPClassic-HC). Is this the original look? It does kind of look like HDR that has not been converted to SDR. Do I need to change a setting?
Master file was SDR RGB 1080p. So what you're getting here is SDR -> HDR -> SDR, and 1080p -> 2160p (via qtec shitty algorithm) -> 1080p. All that for 4:4:4. Not worh it.
@rokweom NO you're wrong, master file delivered to the authoring studio from Shinkai was full range ** 10-bit ** RGB 1080p / 4:4:4, NOT standard 8-bit !

And you just threw qtec didn't you? Show me in the article where they used the same methods as qtec.
@npz yeah, it was 10 bit, so what? Properly encoded 1080p blu-ray still looks better than this.
About qtec, page 3. It's right here. Besides, you can clearly see the usual qtec smearness on UHD BR.
