Picture taking and video recording have gotten unbelievably better over the past decade. They were not remotely sufficient for many use cases ten years ago and even now there's still plenty of room left for improvement.
And "there is a big difference but not everyone cares about it" is quite different from "there isn't a big difference". The latter is clearly false.
Yeah there's some really amazing stuff the new phone can do but I honestly don't care. If I need a piece of correctly specked camera equipment I'd probably buy a dedicated device with proper cooling and a removable memory card.
