Sure, but at times it can depend to what degree and where--for example if it's a minor lag in the weather app when looking at different cities, which is something I almost never do, then it's not likely something that would matter much to me, even if it's there. Taking a more typical user, they probably wouldn't even realize there's some lag when it comes to some animations and movement, let alone perhaps care about it, especially when it comes to something they might rarely use, if ever at all (there are sure plenty of people out there that don't even know what Control Center is, let alone use it in some way, even occasionally).
