I tried to sideload the Android TV apk on my Android Pixel and found out that it works pretty well.
-Local DVR discovery
-Live TV playback
What doesn’t work:
-Remote DVR login (no webpage running on :57000/auth)
-Playback controls (Pause, RW, FF)
Seeing how much of the Android TV app is working on regular Android I’m sure would just take a few simple tweaks to make it a fully functional Android App. Adding on-screen playback controls, Auto rotate / full screen and fixing the Remote DVR login is all I I found that it needs.
