The "problem" with your example is engines. You usually could implement any point and click story in a first person engine (and that one might even be capable of 3rd and 2nd person). And of course, many a first person engine game tries to have platformer elements to the dismay of some players that can't jump accurate in those.
What I would call a change is switching between turn-based and real-time. Those Pathfinder games can do that, but the switch is player chosen. Same as you can chose to play Skyrim in Ego perspective or zoom away to 3rd person.
