I am also on CachyOS and KDE here. It was a good find. Seems to be getting more popular and well known over time.

KDE suports HDR just fine. I believe both Hyprland and Gnome do as well. Those seem to be the most modern DEs generally speaking. Gnome and KDE being the most popular as well.

Edit: Just realized you said mint specifically. Mint are behind the times sadly.
