I noticed this the other day so I wanted to test again with a different movie. I purchased Dune on Apple TV. It is 4K and has Dolby Vision when played through the Apple TV app. If I launch the movie from my "library" and press the button that says, "Google TV WATCH NOW", it retains the digital sound but loses Dolby Vision. There is no HDR at all actually. At first I thought, how convenient?!! It would be awesome to have a few less buttons to press. Unfortunately, I really enjoy Dolby Vision.

Is there a way to fix this?
