View photo memories on Apple TV
The Memories screen in the Photos app 
automatically arranges photos and videos you haven’t seen or thought about in a while. Trips, events and moments are presented in a gallery and as a short movie that you can watch on the big screen.
To get memories on your Apple TV, you need to have photos and videos on another iOS device, iPadOS device or Mac linked to the same iCloud Photos account. The best memories created on those devices will automatically become available on your Apple TV.
You can’t create or edit memories on Apple TV, but you can adjust playback settings such as mood and duration.
