Edit: Thanks for your 8 bit explanation, that makes sense. Yeah I did not think how intel does it for a moment. Curious if I see that with my eyes, from mathematical computation it's sadly a lot.

Off topic - but most broadcast 1080i and 1080p HD SDR content is produced/mastered in 4:2:2 10-bit SDR (and has been for a while). When you see 8-bit h.264 4:2:0 as it arrives in the home, covered in 8-bit banding (not helped by heavy compression), and compare it to the 10-bit broadcast master, particularly on demanding content, it's like night and day sadly.

I've remastered some SDR 1080i25 4:2:2 10-bit AVCi100 100Mbs broadcast masters (in my day job I deal with broadcast video) to SDR 1080p50 or 1080p25 4:2:0 10-bit HEVC/h.265 at a decent bit rate - and they look great. (HEVC/h.265 10-bit decode and playback support isn't just for HDR )
