Which distro has full HDR support?
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.
Last time I checked only KDE and Gnome support HDR. (For gnome it is still experimental)
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.
as far as I know you still have to set environment variables and use gamescope with a flag to enable it for games, but general desktop stuff anything with kde and I think also gnome will have a checkbox in the display settings.
