Materialism, idealism and panpsychism are all non-scientific metaphysical claims, at least as they are normally argued about. Nobody typically makes any claims how world would look any different it one of them turned out to be true rather than any other of them. Sometimes they maybe do, but then they'd be better off not using these wishy-washy metaphysical terms at all and clearly stating their hypothesis. Since they are not necessarily talking about the same thing as other people who nominally subscribe to the same -ism.
The same goes for dualism, though I have my own ideas how an interactionist dualist world would look experimentally different. But again that might be just my own interpretation of the idea.
