Just discovered a Special edition change?

I was working on my 4K77 preservation, and I noticed something it this shot of Artoo turning his head. It seems that you can see the fingers of someone spinning their head with their hand. And at first I was like “that’s cool.” “Never seen that before.” Until I looked at the Blu-ray,y AND IT’S BEEN DIGITALLY REMOVED! I checked the visual comparison website, and it isn’t there either. Has anyone else seen this?

4K77 (degrained)

2011 Blu-ray (color corrected)

Is that Kenny Baker? The resolution of the image does not make it clear what is being looked at.

It’s someone’s fingers. Definitely not Baker, as he would be inside Artoo.

You mean there is someone below frame under Artoo? Weird.

Behind him. Remember Artoo is much bigger in person.

Dang it! His motor died. . . Jeff, get over there and spin the dang thing!

Most likely what actually happened.
