Is this problem new, or did you experience it in 6.2 as well? If you set the color profile to "built-in" with HDR disabled, is the result similar to when HDR is enabled? Does your monitor have any color profile settings itself? Some "helpfully" change the settings when in HDR mode. Do you have a Windows or MacOS system to compare the image to? Sometimes displays just have a terrible HDR mode. The black levels on your images look quite bad, could that just be the monitor driving the backlight at 100%? If you set the brightness to 100% in SDR mode, do the black levels look similar?
(In reply to Zamundaaa from comment #7) > Is this problem new, or did you experience it in 6.2 as well? No. I've seen this since ever. I don't recall it being better in the past, but I don't have an exact starting point (Plasma version) to say when I started using HDR.

Checkout these videos I made: https://cloud.smirky.net/s/LwpRjr4eCLRzrie Unfortunately, you might have to download them, because Nextcloud's video player lacks proper browser playback in certain browsers. First video is with locked exposure on my camera, second is with Auto. Let me know if you want to try something else, I'm open to suggestions. (In reply to Zamundaaa from comment #7) > Does your monitor have any color profile settings itself? Some "helpfully" > change the settings when in HDR mode. The monitor has HDR and non-HDR modes in its settings (called OSD menu). HDR is currently enabled and also set to Auto (as per a video I checked, it should be set to Auto to avoid problems). The brightness and contrast settings become grayed-out when HDR is on Auto. In the OSD menu, Color section, there's an option "Color space", which is currently in HDR. If I change that to something else (for example sRGB), it becomes unbearable and way worse. It also disables HDR.

Unfortunately, I don't have an available Windows PC/Laptop with a Display Port.
Reopening.
While not as good as checking another OS entirely, we can at least test if it's KWin's fault or if either monitor or GPU driver are messing things up. If you start gamescope in embedded mode from a tty, like so: > gamescope --hdr-enabled -W 3840 -H 2160 -e -- steam if that looks the same as on the desktop, then there's likely nothing we can do to fix this.
