The Amazon Prime app for Apple TV has some great features (e.g.: X-Ray tells you the actors in a scene when you pause) but is the cheapest-looking app I’ve used on any platform in decades.
@gruber sadly the Apple TV app still doesn't support Dolby Vision. I have to use my TVs app to watch Amazon shows in the best quality.
@lukehorne @gruber Is that why the picture has this weird grainy rainbow effect on the Apple TV?
