FWIW, thats true even for the older gen 4K and even the HD ..App switching is also fast .. In the sense that if you have X open on prime and you open Y on netflix.So the best thing about Apple TV for me is, it takes 2 seconds to switch on and resume the last app that was open. Not fair to compare it with a 4 year old Fire TV but mind blown.
Switching back to prime will bring you to the state you left X in (e.g. paused - rather than taking you back to the Prime home screen)
But it better do that at 3X the cost!
BTW that 2 sec resume would be from sleep
