How can I have a Flickr screen saver with latest tvOS?

Hi. We're contemplating getting the latest Apple TV set-top box.

Right now we're still using the 3rd-generation model, which actually works just fine for our needs. I really like the Flickr screen saver that's built-in to that model; it allows us to specify particular Flickr groups that are of interest, particular search terms, etc. It's great.

Would the latest Apple TV, running the latest tvOS, allow us to have that same screen saver? I know it's not there by default. And I know there is a Flickr app for tvOS—does installing that app add the option for the good ol' Flickr screen saver?

This is actually a major factor in the decision of whether to migrate to the latest Apple TV model.

Thanks.
