P: Ability to use albums as Apple TV screensaver

I would really appreciate a feature like that. Would be nice to be able to have an album or all pictures as a screensaver. Now I use the publish function in Lightroom to get the photos I like as a screensaver. But it would be so much simpler to have the feature in Lightroom for Apple TV. 
Better transitions for slide shows is another feature I would appreciate. 

I would like this ability on macOS itself.

For now, you can save your chosen photos to iOS Photos app, which automatically creates a "Lightroom" album. Set that album as screensaver. Any photos you save to camera roll on your iS device will be synced to the wallpaper album. that's my workaround.

ATV LR App needs a huge update to be a better showcase app. 

Going from grid to Detail view and going through photos and the exiting where you entered, not where you finished watching makes no sense and makes the app unusable.

Add option to view photos from the same day after search, add ability to filter properly, add nicer slideshow options. Please, adobe, don't kill the app.

I'd love also to see this feature.  The Adobe LR app on Apple TV is nice, but screensaver capability would be excellent.
