Are the matrix details the EXACT same on both copies?
I did some close comparisons of the printing style in your scans. Check out the pictures below. Everything above the red lines is taken from the copy without arranger credits, and everything below the red lines is taken from the copy with arranger credits. It looks as if the label on the copy with arranger credits has been copied and the edges of the text are a bit bloated/blurred. Not that it proves anything, but it's interesting to see two copies scanned with the same scanner side by side.
