A wide selection of Disney movies are showing as available in 4K on the iTunes Store as of today in the United States and Canada, including many Marvel, Pixar, and Star Wars titles. However, not all movies are listed as 4K at this time.
iTunes Store content became available in 4K in 2017 in time for the launch of the Apple TV 4K box, but Disney movies were a notable exclusion.
This isn’t the first time that the 4K label has showed up on Disney movies in the iTunes Store, with previous instances proving to be false alarms. In this case, however, the 4K label has shown up on a wider selection of Disney movies across multiple devices, including the iPhone, Apple TV, and even the Apple TV app on third-party platforms like Roku.
Disney movies are not showing up in 4K in all countries. In the United Kingdom and Australia, for example, users are still seeing playback limited to HD.
