@123hest The problem is that the Apple tv 4k will not be released until Nov. 2nd.
Until then, only this screensaver is availabe in 4k.

Once the new ones come out, I'll make them available too.
Also this is not just the opening scene, its one screensaver out of many.

Hi, Disrespect Woamen
I've been trying to find the apple 4K aerial shoots, and this is the only wallpaper (or video for that matter) in proper quality I've been able to. As far as I can tell, this is only the opening scene. Where did you get this from, do you have the rest, and are you planning to upload them?

Thank you for the great wallpaper though!
