Apple has started introducing 4K HDR movies on the iTunes Store. You’ll be able to buy or stream the content on the new Apple TV 4K set-top box, which can be ordered now and is due to arrive next Friday — if you’re lucky.
Not all titles are yet available in the 4K HDR format and not in all regions. Apple is beginning the roll-out in the U.S. And, as noted by AppleInsider, notification of support isn’t yet system wide; some movies display “4K” and “Dolby Vision” icons on iOS, but lack those assets on macOS.
