> and can be enjoyed on iPhone, iPad, and the new Apple TV 4K But the old Apple TV 4K is not powerful enough for displaying text on a TV, even though any old iPhone is? I get that they want to push device and service adoption but they should pick a lane, either push users to upgrade devices, or push to sign up to paid services. Pushing for both at the same time is greedy.
So I wouldn't be surprised if it relies on a particular hardware chip that the older Apple TV simply doesn't have. That has definitely been the case for everything Apple has launched with regards to Spatial Audio.
