I have a 2016 MacBook Pro with the most recent versions of High Sierra and iTunes. Why is it that when I go to the iTunes Store and browse movies in 4K the actual movie never indicates 4K? The same movies do show 4K icons on my iPhone, iPad and Apple TV 4K. The screenshot if from iTunes on my MBP and as you can see it does not indicate that Spider-Man Homecoming is in 4K despite having clicked on it from the iTunes 4K section.
