non-standard UI elements are quite visible - modals, progress indicators, tabs also everything around navigation is trouble - ios has those large headers that shrink down once you start scrolling. For a long time this was not possible in RN, not sure it finally is. iOS 15 also uses modals quite a lot more than previous versions. Including modals on top of modals. Also impossible in RN up until recently, don't know current status. While the navigation-related differences might not be consciously picked up by normal users, it may be subconsciously felt - the app doesn't feel right and user doesn't know why.
