I don't have an HDR display, but I do have two high color gamut displays. And when using Linux and my displays set to Adobe RGB all the colors on the screens look neon because color management in Linux (Windows, too) only adjusts LUT values. Only apps like Krita, GIMP, Blender, Firefox (after manual configuration), etc. show correct color. It's pretty annoying. Hopefully that'll change one day.
