Did valve just release the first Linux distro with HDR?

Well, technically they're only about to, as this is the preview version.

Interesting, I didnt think the lcd would have supported hdr

Patch notes says "HDR can now be enabled in Display Settings if supported by the external display."

Ohh wow... Is this the first proper Linux HDR implementation?

Hopefully it spreads to desktop too

There was a HDR hackfest earlier this year. A couple of reports from after the event if you're interested https://emersion.fr/blog/2023/hdr-hackfest-wrap-up/ + https://blogs.gnome.org/shell-dev/2023/05/04/vivid-colors-in-brno/. It also got a brief mention in the System76 blog https://blog.system76.com/post/may-flowers-spring-cosmic-showers.

So it's being worked on, and it seems all involved are trying to get it right - it sounds like gamescope on SteamOS doesn't need to worry about solving all the problems that general purpose desktop compositors will have to.
