I wonder if a U1 UWB chip be precise enough to detect if if the ATV has moved. Using 1 HomePod mini as a reference point, and more precision with more HomePods.

The location of the screen could be learned with some "Apple Magic," i.e. an AR setup process using an iPhone

All they need is a "look at your TV" step. User looks at TV, ATV saves AirPod gyro orientation and you are done. The iPhone/iPad need their orientation because the screen can move at any point...TV's usually don't.
