An interesting point. I’m very unsure of this, but I think that the main difference between IV and V is that V includes measures to prevent introduction of Martian life to Earth. The mission to collect the prepared samples would certainly be a category V according to my understanding. Perhaps the crew or lander collecting the samples would first have to do some sort of examination, assuming Perseverance hadn’t already?
