Adobe:

With this Lightroom for Apple TV release, you’ll be able to share your photos one by one in a slideshow, with the ability to stop and zoom in to see all the detail within your photo. Quickly navigate through all your photos to find that exact memory you’re looking for.

All your photos, are always available with your latest edits. In Lightroom for Apple TV, you can view and share all of your synced Lightroom photos including photos you’ve uploaded via Lightroom CC on your desktop, Lightroom on mobile, or Lightroom on the web.

Lightroom for Apple TV requires an Apple TV 4th Gen as well as a Creative Cloud subscription to login. The app can be downloaded for free from the App Store on your Apple TV, and is available right now.

I use Flickr right now as a way to show off my images on an Apple TV but this would allow me to keep up with any edits I may make to them.
