It looks like the next Apple TV 4K is ready for 8K

Evidence has been found in the code for Apple’s next big round of software updates — including for iOS on phones, iPadOS on tablets, macOS on Macs, and of course tvOS on Apple TV 4K — that Apple will support the next-generation AV1 video format on its own. devices in the future.

AV1 has one major advantage: it is more efficient than current video codecs (a ‘codec’ is the algorithm by which a video is encoded for streaming and then decoded for display). This means you can use less data to stream video at the same quality, or you can use the same amount of data to stream even higher quality video, such as supporting 8K without using tons of data.
