Depends, if it's React Native it's actually getting hard to tell with all the work they've done to UI performance and animations etc. Flutter or a wrapped web site on the other hand are immediately obvious to me, in fact there's a certain flavour of Flutter jank in lists that is an obvious tell. I can also tell when an app's using SwiftUI due to the presence of a particular navigation bug so "native" toolkits don't get a pass here either.

I'm not sure it's pretentious it's just those developers are close to the topic and have opinions about it - you see it in other areas of software development too.
