Look closely. Right after you’ve swiped up from the lock screen, soon after the icons fly in pay attention to them and you’ll see them subtly ‘bounce’ back out (or fly back out). It is very subtle though. I don’t usually have a parallax effect with updating but this one I noticed. Unless it’s always been there and I’m only noticing it now because I’ve updated.
Ooh yes...a tiny bounce back by the icons. Well spotted!
