TL:DR the animation is much smoother in 10.1 beta 2, but is not as smooth as phones with a physical home button
i recommend downloading beta 2 if you want to get rid of stutter when leaving an app.
just updated to beta 2 from 10.0.1 on my iphone 7 plus. seems like the stutter is smoothed out. there still an different animation compared past iphones. i think it has something to do with the force touch home button vs the physical button.
when you press once. the app starts to close instantly, but it does it slowly then after a few milliseconds, it speeds up and gets back to the home screen smooth and quick.
when on any phone other than the 7 or 7 plus, the animation does not start slow then picks up speed. its just one solid speed transition from app to homescreen.
if you have a iphone 7 or 7 plus and have a past device (6s 6 5s) open an app on both phones, then close them at the same time and you should see what im talking about. if not try getting a third device and film your self closing a app with 240 fps slow mo recording. you'll defently see what im talking about
ill try talking a video side by side over the weekend when i meet up with my bud. he has a iphone 6 plus so i can show it versus my 7 plus and show what im talking about.
