pwt is an interpretation. All interpretations of QM share the same mathematics .. or effectively the same maths. Different "interpretations" cannot produce different predictions in experiments. So using an experiment designed to emulate pwt (which afaik violates special relativity) can only say one thing possibly - that if we find it convenient to think in this way in some limited cases of quantum mechanics, we may do so. In other words, it may at best serve as a heuristic to teach children, that they can later grow out of.
