Benjamin Mayo maintains a page that lets you view all the various Apple TV screen savers, with the ability to switch to your screen saver of choice and pause and scrub through as you like.
The Apple TV periodically fetches new videos from an Apple server. This page interprets that data source and shows all the possible videos that the Aerial screensavers can include. This page is automatically refreshed and kept up-to-date as Apple adds new videos into the rotation.

As part of the tvOS 15.2 release yesterday, Apple announced it was adding new Apple TV screensavers featuring aerial flythroughs of Iceland and Scotland.
