Have you seen some of the new HDR stuff on KDE plasma 6? Still early days, but very exciting!

https://zamundaaa.github.io/wayland/2023/12/18/update-on-hdr-and-colormanagement-in-plasma.html

oh that is interesting! sounds very promising.

“SDR Color Intensity” is inspired by the color slider on the Steam Deck. For sRGB applications it scales the color gamut up to (at 100%) rec.2020, or more simply put, it makes the colors of non-HDR apps more intense, to counteract the bad gamut mapping many HDR displays do and make colors of SDR apps look more like when HDR is disabled

I guess this goes some way to answering why colour accuracy for SDR content was so dodge when I turned on HDR on windows (which lacks such a slider, just a brightness slider). "the bad gamut mapping many HDR displays do" is big oof but also explains a lot. the mathematics for colour space transformation is pretty well-defined, so if hardware is implementing them incorrectly, that's really frustrating. older screens are working with standards that predate the idea of colour management, but now we're bringing in all these new display signalling standards (PQ and all that), it seems like a golden opportunity to do things properly this time... so of course we don't lmao.

the colorimeter I got has an option for high brightness/HDR screens, but I haven't really tested it yet. 'measure your screen colorimetrically and compensate in software' works decently well in SDR land, but I'm not sure what happens in HDR. I haven't played any HDR-enabled games since I got this colour accuracy bug, so I haven't had cause to try and figure out the ins and outs of it yet.

it seems like KDE intend to be a lot less black-box about it than Microsoft, which is very welcome.
