I have no idea what you mean by this.
I'm saying they are both the same, ie an attempt to reboot the Compuserve animated GIF format. Vine is another one to try the same thing, except 6 seconds long. So neither Apple or Nikon are the originators of the idea as per the OP's suggestion that Nikon deserves the credit. And nor are either the first to try to re-boot the GIF either.
The difference is simply the approaches they've taken; one adopting a video file forma similar to Vine, the other a sequence of JPGs animated like an old fashioned flip-book, which is actually closer to the original GIF concept.
Edit: Even JK Rowling rebooted the animated GIF before Nikon did. Apple actually acknowledged Harry Potter in their keynote, and I suspect Nikon should have too.
