iTunes movie purchases, video quality
None of my iTunes purchased movies will play in HD. I have checked my streaming and download settings, they are set to stream/download in the highest available quality. I've tried to stream/download the movies on my iPad Pro and MacBook Pro using the TV app. Both give me the same result, standard definition.
*The only movie purchases that will play in HD are the ones that are available in 4K Dolby Vision.
