Disney Movies were previously available on Apple’s iTunes Store in a maximum of 1080p which was quite watchable though, however, the things have changed now, for even better video quality users can now purchase or rent Disney films in 4K video quality which is the maximum quality available as per the latest technology. According to the details on The Verge 9to5Mac first witnessed the change, which applies to several countries including the US. Disney, Marvel, and Pixar content are all included — though not every movie seems to have made the switch to 4K just yet, the movies should also support 4K video quality in order to get in this version.
According to this Reddit thread, the Star Wars saga and several Marvel flicks (plus some animated classics like Aladdin) already have.
Disney’s films have been offered in 4K on other platforms including Vudu, and if you purchased them there, you should now see that 4K quality carry over to Apple devices thanks to Movies Anywhere. Similarly, if you now buy a Disney title in 4K on iTunes, you should get that version on at least some other apps that support Movies Anywhere.
Apart from the uptick in resolution, many Disney movies on iTunes now also offer Dolby Vision HDR and Atmos surround sound. That puts the experience of renting or buying them from Apple on par with streaming those films through Disney Plus, which has offered a large collection of Disney, Marvel and Pixar movies in 4K HDR since its launch last year.
