Guys,

would love to get some data from real usage. If you feel brave enough you can flip Firefox HDR support and try that. You don't need an actual HDR hardware, HDR conversion is done at compositor level.

On it.

Thanks for testing.

I run HDR mode on Firefox on both AMD powered desktop with an HDR monitor and a convertible laptop with sRGB screen using Display P3 for colour management. On desktop, playing a video on You-tube, HDR is properly detected and used. It seems HDR images are unsupported at this time of writing
when tested on jpegxl.info and

Yes, exactly. Only HDR video is supported right now, rest will come with updated internal color management for all platforms.

Thanks,
Martin
