Kai, it seems to be generally agreed between those people who are supposedly expert in these matters, that where material objects exist in Javanese sculpture from these early periods, those material objects do in fact reflect what was in use in the community at that time.
As to whether or not this sculpture actually did originate during the Mojo era, it is as I have already said:-
it is in a museum that exists for no other reason than to preserve and display Majapahit artifacts
it was found in the central area of Majapahit, and noted scholars consider that it is Majapahit work.
I might be a little bit naive and perhaps too trusting, but all of that is good enough for me.
