Comment (by Peyton Lee):
Replying to [comment:1 MasterQuestionable]:
I'm not entirely sure about the composition of HDR .PNG files, but when
playing HDR videos, the video post processor needs to recognize that the
video is in HDR format in order to perform HDR color transformation.
Skipping this step would result in a darker color rendition on screen
during playback.

content may already make:

unnoticeable).

indistinguishable.
