This has the same issue as most screenshot software, it's out of date relative to modern devices. Every Mac laptop for the last ~4 years has an HDR display. Many windows devices are also HDR. But this app doesn't capture HDR.

I tried putting up an HDR image and then capturing the screen. All HDR brightness was gone from the image.

I get it's not easy per-se. It wasn't until MacOS Tahoe that Apple's own screen capture on Mac started supporting HDR. Windows 10/11, AFAIK, only supports HDR through the XBox Game Bar's capture. Apps like ShareX still only capture SDR.

I mostly bring that up because I have apps the draw HDR and spent some time trying to find ways to add tests that we're actually getting HDR on the screen using screen captures. I hit a wall and gave up (2021).

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 That readme might be outdated (or the tool doesn't work on KDE at all)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		Yeah I think I’m a bit outdated here.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

>But this app doesn't capture HDR.

When you say the Xbox game bar accounts for it, do you mean video or still images? I've had HDR disabled for some time but I remember win+shift+s on Windows 11 capturing over-exposed screenshots when playing videogames.
