Is WGC breaking Widows AutoHDR when streaming?

[h107474]

So I have moved from Apollo to Vibepollo and to the new WGC. I noticed a strange issue now I think may be due to the WGC but can't be sure:

In Apollo in games that can use Windows AutoHDR, it works on the stream as it does on the host. This means it increases brightness into the HDR range and this can be checked/adjusted by bringing up the Game Bar overlay and moving the AutoHDR intensity slider. Moving this changes the brightness of the game behind the Game Bar overlay.

Now in Vibepollo, I noticed the streamed game is much dimmer when using AutoHDR and bringing up the Game Bar overlay the AutoHDR intensity slider does nothing. However, if I go into the main Windows Display Settings and change the desktop SDR to HDR brightness slider inside the HDR settings page, the game now changes in brightness with the desktop slider.

This is not how it is supposed to work and this desktop SDR to HDR brightness is capped to a lower peak brightness vs the gaming AutoHDR so this is not an ideal work around.

Shall I move this to the Issues section rather than Discussions section?

I have the same issue with RTX HDR, it is not applied when streaming and using virtual display. Everything is set up correctly.
