I’ll remind you, for the record, that some  here were advocates of using the XYZ color space for encoding (as opposed to BT.2020) - https://forum.blu-ray.com/showthread...z#post15497298 .
And also something I think may not have ever been reported is that Pat Griffiths of Dolby Labs actually wanted 20,000 nits for PQ. |
Yes XYZ coding would be even better encompassing all but I guess 2020 was chosen because the primaries were within the visible and they could "visualize" it instead of dealing with "imaginary" out of bound colors?
But funny thing it's basically the same as doing P3 inside 2020, they could have "done" 2020 (or any gamut) inside XYZ as it's just numbers and equations and color management would dealt with it, since we're doing it now with P3/2020 anyway.
Maybe later?

About 20k+ nit highlights..
well if they code highlights up to 1023 limit in the video, above the legal 10k nits 940 level.. doesn't Griffiths gets his wish? Unless it makes the player->monitor playback go like this:
