They look the same to me. The Black Series helmet was fairly small as well, and the Disney helmets have all of the same details as the Black Series, it even has the indented "sliced onion" graphic on the side, which on some helmets has a sticker applied over it to try to change the graphic. All of the greeblies appeared to look the same and attach the same as well, and if I remember right, I seem to remember noticing what looked to be a place where the switch once was. But I'd have to have both helmets sitting next to each other to be certain of that.
