I mean, it is dead simple after all

Also Hyprland… Yes, that’s the key - the desktop, not the distribution, though the „stable” distros don’t yet ship stuff new enough for this.

Yes, because back when I was learning almost 20 years ago I was able to google terms and read stuff for myself and it was also requirement for posting on forums, yet I was still getting a lot of help from the community. Times has changed it seems, so did the culture. Should I always assume ignorance and lack of interest? And now before I saw your comment I responded more comprehensively anyway, because why not, I’m not mad or anything. Should I take more time to write the response the first time around? Uh maybe idk

Desktop environments or window managers that support Wayland (one of the two displaying systems for Linux, newer one with aim to replace the obsolete one) and already implemented color management protocol in their compositors (programs that compose the image that is being displayed).

In essence, everything that has recent version of Plasma 6 or current version of Hyperland is able to do HDR. Soon there will be new version of GNOME that does that too.

Sooo… not Linux Mint, not Debian stable, not Ubuntu LTS.

Every single one that ships Wayland compositor that supports it. I’d say „finished” is still a bit of a stretch though, since HDR support in apps is still quite limited and the only way to play Windows games with HDR is via Gamescope.
