Match Dynamic Range issues after latest update

Running Channels on Apple TV 4K connected to an LG OLED. After the latest update, the Channels app is no longer matching dynamic range. Settings for the Apple TV still have match dynamic range on. Have tried restarting the app, the TV, and the Apple TV but no change and the match dynamic range setting is working properly on other apps.

Latest release version? Or latest beta from TestFlight?
