Lightroom Apple TV: Ability to access our catalog on our home computer

Sharing photos with TV is the main reason I use creative cloud version of Lightroom and LR Mobile on the TV. Direct-to-desktop access like you suggest would be great if it meant:

1. Viewing higher-resolution versions of our photos (up to 4k resolution to match 4k capabilities of TV and AppleTV).
2. Viewing of our videos (stored/organized in LR catalog) on the TV.
