Photos displayed on Apple TV are washed out
My Apple TV correctly displays video content, including HDR on my TCL Roku TV. However, my photos in Apple Photos and iCloud, which display correctly on all other devices (Macbook, iPhone, and iPad), appear dull and washed out when they are displayed on the Apple TV as a screensaver.
Is this normal? Is there a way to display photos on Apple TV correctly?
