I set gfx.wayland.hdr to true and tried opening this video. It says HDR around the cogwheel, but the colors are washed out. With this option disabled the video looks great.

I tried enabling other options, like native_srgb and compositor as suggested online, but no difference.

    I use it with Arch & KDE. Just enabled HDR in display settings and did the calibration. Only issue I had was with cyberpunk, couldn’t get hdr to work properly (seems to be a known issue). Works with other games I’ve tried, youtube hdr videos, and mpv hdr movies.

    Edit: I tested your link (as well as other hdr youtube videos ) and it was washed out. I remember watching that exact video before to test my monitor. I downloaded firefox 144 and it worked properly so I think something in 145 broke youtube hdr in linux.

      I just managed to get Cyberpunk with HDR working. I downloaded Protonup-Qt, installed GE-Proton10-25, selected it in Steam and added PROTON_ENABLE_WAYLAND=1 PROTON_ENABLE_HDR=1 ENABLE_HDR_WSI=1

      I downloaded firefox 144

      Hmm… It’s still washed out for me If I downgrade it.

    It works on Fedora 42 with KDE just out of the box with the GUI display setting for me, but I frequently need to rebalance the brightness with the wizard KDE provides for HDR brightness, it fucks up and gets very dark until I redo that every N times I turn the TV off and on again.

      I’m also on Plasma 6.5 and I set HDR to enabled… So you didn’t enable the toggle in about:config? In my case it shows the video on SDR.

        Oh, I meant overall, not specifically in Firefox, I’ve only used video players directly for HDR, not web players (idk where I’d even find HDR webplayer content tbh)
