Steps to reproduce

Enable HDR in windows, and increase SDR Content Brightness in HDR settings. Visit https://www.whitescreen.online/pink-screen/ and check the live capture.

What is expected?

HyperHDR to capture colors correctly

What is actually happening?

HyperHDR screen grabs are overexposed. Website I am using to test https://www.whitescreen.online/pink-screen/ . As a result, LEDs also show white in these cases.

Screen capture when the setting is at minimum

Screen Capture when the slider value is increased

The pink color clips. The settings "HDR to SDR tone mapping" and "HDR brightness correction" have no visible effect on this problem. I am using an OLED monitor which is capable of true HDR and shows proper colors, regardless of the SDR Content Brightness setting.

This is not a bug: such fancy Windows 11 features that interfered with default color management were never supported, as in this case https://github.com/awawa-dev/HyperHDR/discussions/924 If adjusting the brightness level in HyperHDR DirectX configuration panel doesn't help, then I don't currently see a way to work around this issue.
