AppleTV does not play purchased movies in HDR/Dolby Vision
My external AppleTV will not play my purchased movies in their native HDR/Dolby Vision format. It will only display them in standard definition. However, the AppleTV will play movies from other apps (ie - HBOmax, Prime, etc.) in HDR/Dolby Vision.
Please help, I have a good number of purchased movies that I cannot watch in the correct format.
