Comment (by Balling):
So further comment here: profile 5 is only using IPTPQc2 if it is not
marked as HDR10 compatible (see Mediainfo), in that case it uses limited
and not full range. We do not, AFAIK, yet print that data (or print
compatibility ID wrongly). For example these Apple 4K profile 5 videos are
not IPTPQc2.

Also mandatory full range IPTPQc2 does use Y' of 1 for pure black, as can
be checked by
ffplay -i file -vf extractplanes=y
There is also now Avengers Endgame from Display+ available with IPTPQc2 on
torrents with very high bitrate.
