Not my experience. When I don't care about audio quality then I find the Apple TV video to be better - sharper, brighter on my OLED.
Shield is now running video promotions on the app selection page. Very annoying. Apps in the Google app store don't seem to have the same quality as those on the Apple TV.
I didn't keep a list of the problems. If you don't mind waiting I will update them when they occur. Its not that their frequency makes it unusable, it is just there are more than I experience on my Apple TVs.
