Hey there,
I tried to publish my app inventor app in Play Store for Android TV. I tried via Sideload first and it worked well. Anyway google wrote:

It's all hail Google if we want to have our Apps on Android TVs

It's about Android TV expecting certain launcher code in the manifest and a specific type of icon.
