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.
