And the only thing I think we know for sure about the DCP release is that it had the animated robotic hand. It’s not known if it has the extra speeder. Presumably the Padme lines that were changed later that year for DVD (‘is to be human’ and ‘uh huh’) were the same between DCP/35mm, since those scenes were panned by critics and it would have come up if there were different versions to be seen (and this also explains why they were indeed tweaked for the DVD).

A 35mm print would settle whether or not Jango had extra sparks added to his jet pack, but I think people are mostly in agreement that there’s no difference. Seems like just a weird assumption or false memory.
