Amazon Firestick, Apple TV App and Dolby Vision
My LG tv can display Dolby Vision programs/films. I have an Amazon 4k Firestick plugged into my TV. When I watch any film I have purchased on the APPLE TV app via my firestick and the film has Dolby Vision available my tv does not indicate that Dolby Vision is being broadcasted. If, for example, I watch a Dolby Vision film via Netflix, The Dolby Vision symbol pops up on the top right of the TV screen. How do I know/tell I am watching in Dolby Vision via the Firestick/Apple TV app?
