Description
- MPV build by shinchiro (20211128-git-f08db00)
- Win 10 with custom icc profile made with displaycal and wide gamut monitor
When playing a rec2020 hdr file, colors get clipped to rec 709 instead of fully using my monitor native gamut, so it looks like i'm viewing the content on an srgb monitor. Rec 709 content instead works perfectly and doesn't get over saturated.
I'm running these commands: icc-profile-auto --audio-exclusive=yes
P.S. on hdr input, blacks also get crushed/cutted

Research direction
Reproduce the issue on Windows with the reported mpv build, wide-gamut monitor, custom DisplayCAL ICC profile, and a rec2020 HDR file using the provided command. Compare HDR and rec709 playback, including gamut handling and crushed blacks; done means HDR content uses the monitor's native gamut without clipping or black-level loss.
