The second image is my corrected version of that frame, which is a combination of the Blu-ray and -1’s release. It is a confusing comparison, apologies.
And yeah, it’s bizarre. My guess would be that whoever was working on it cut out as much of the frame as they could, then forgot about it, since the parts from the original frame don’t even have similar coloration.
Here’s another single frame issue that I’m not sure has been found yet:
This flash from the beginning of the gun turret battle is not in the Blu-ray, though remnants of it can still be seen. It is however in Silver Screen and GOUT.
