Nebula for Apple TV on LG Smart TV

I appreciate the quick response. The issue is that I'm accessing AppleTV on my LG smart TV, and the menu organization there seems to be substantially different than it is on the standalone Apple TV. (I can select Apple TV from the LG home menu, but the Apple TV App Store does not seem to be available from within the Apple TV app. And of course the LG app store equivalent does not stock Apple TV-specific apps.)

Yeah, gets really confusing. Appreciate your help.
