Don't use dev windows build. If use - don't write any issue.
Windows 24H2 is released in the Retail channel on arm64 (for Copilot+ PCs) and the amd64 Retail channel release is imminent.
I don't have arm64 PC.
It's in the Release Preview channel (not dev) for amd64 if you fancy having a look.
Expecting Retail channel any day now.
This is the first app that I know of which has resolved this issue: https://github.com/res2k/HDRTray/issues/13

Install this version of Windows, write code, test, send a patch :)
I obviously don't have it either yet. I am just linking to the code patch so you can easily find it when needed.
Windows 24H2 Build 26100 has a new option which seems to be confusing all HDR mode switching utilities and media players, including MPC Video Renderer.
The new option "Automatically manage color for apps" under "System > Display > Color Management" increases the color range of Windows SDR to HDR levels to remove things like color banding. It works great and is very noticeable throughout the Windows UI but a side effect is all apps think they are already in HDR mode, when they're actually not. With this option enabled the only way I've found to switch Windows HDR mode on and off is with the toggle in Windows settings.
MPC Video Renderer is unable to switch to HDR mode from SDR mode when "Windows HDR: Allow turn on" is enabled in the settings.
