Apple TV 4K Background

Try setting a non-aerial screen saver, activate it once, then set back to Aerial, and let it get new clips over the next couple of days. That is as close to a reset as you can get for just this feature.

Leave it on to allow for downloads to happen (it won’t download anything in sleep mode).

Greetings, isabellawylie.

Welcome to the Apple Support Communities. We can understand why you’d want to change your Apple TV 4K screen saver. 

It looks like you contacted us using this resource: Aerial screen savers on your Apple TV 

We also, suggest reviewing your screen saver settings. 

“Open Settings  on Apple TV. 

1. Go to General > Screen Saver, then do any of the following:

• Choose a different screen saver category: Select Type, then select the screen saver category you want to use.
  • If you choose Apple Photos, choose one of the photo-based screen saver themes.
  • Show or hide different Aerial themes: Select Themes, then choose any of the screen saver scene types to show or hide. For example, you can hide all underwater scenes.
  • Change the Aerial screen saver download frequency: Select Download New Video, then choose an option.
  • Set the screen saver delay time: Select Start After, then choose a number of minutes. This instructs Apple TV to automatically start the screen saver if the device has been idle for the specified duration.
  • Turn screen savers on or off during playback of music and podcasts: Select Show During Music and Podcasts.
  • Preview a screen saver: Select Preview.” Use Apple TV screen savers

We hope this helps! Thanks for being a part of the community. 

Sincerely.
