The readme suggests this is a Linux-first app and as HDR basically doesn’t work at all on Linux(?) I don’t think it’s very surprising that this app doesn’t handle it.
It does a great job for my purposes – describing which buttons to click over email or im.
Haven't used this app for ages, but yesterday I fine-tuned the HDR settings for my newly bought laptop under KDE/plasma, definitely on Linux. That readme might be outdated (or the tool doesn't work on KDE at all)
My understanding of the landscape currently is that KDE Plasma is the only major DE that supports HDR. I use it for Steam for that reason.
Yeah I think I’m a bit outdated here. But I do think Linux hdr support is weak enough that many Linux-oriented apps are unlikely to do it well
HDR videos and games (both native and proton) work in both KDE and Gnome (and supposedly Sway and Hyprland, but I haven't tried either). I think support in KDE/Gnome landed in a stable release ~6 months ago.
The HDR experience on KDE is about as good as the Windows one. Last time I tried Gnome, there was no way to configure SDR and HDR brightness separately, but it was definitely still usable.
