How do I stream Amazon Video in 4K on Apple TV? (Netflix works but not Amazon)
I have an Apple TV 4K running tvOS 11.3 and a 4K TV.
I can get Netflix streaming in 4K without a problem, and when I swipe down on the Apple TV while playing, the info screen says 4K, Dolby Vision (etc).
But when streaming supposedly 4K content from Amazon (eg Bosch), I swipe down and it just says HD. What do I need to do differently between the apps?
Also, is there a way to tell within the Amazon Video app which content is 4K/HDR?
Thanks for your help.
