Note that some TVs remove 3:2 pulldown automatically. Coupled with the fact that many people don't notice it, I would say auto frame rate switching is very overrated. That's why probably Google certifies boxes that don't implement this feature - it's considered not important.

That's a very USA centric view of the world which is fine for USA viewers and a USA company like Google that only has to deal with 24p and 29.97 fps video content in Android.

Those of us in Europe, UK, Asia, NZ and Australia have to deal with 25 / 50 fps (TV) content as well, and that does not playback smoothly at all when output at a fixed 60 Hz.

Android TV being a niche OS gets no where near the same level of App developer support. That is the reality of the situation.
