Steam Deck OLED is getting HDR streaming back.
Valve has re-enabled HDR in Steam Remote Play with the latest Steam Beta update, after temporarily disabling it earlier this month because of brightness issues that could make streamed games look overexposed.

>A brightness slider has been added to the streaming overlay
>HDR capture now works through PipeWire on desktop Linux
>HDR streaming from macOS is now supported
>Android 15+ phones can stream HDR through the Steam Link Beta app
