A fragile way would be to see what other drag types are being put on the pasteboard. I imagine Finder has some esoteric old types for backwards compatibility and I would guess that Aperture has some image types that the Finder wouldn't normally use (except maybe for picture clippings)
But as Steve said, why should it matter?

The pasteboard doesn't seem to guarantee any that information, although some sources will occasionally have unique pasteboard types that might distinguish them, but only as an exception.
