Ernst,
I was thinking in a similar line. If the films scans were ever converted to Jpeg files, many of these subtle tones could be lost in the compression, then decompression of the file. Also, he didn't mention files size. Enlarging a small file could also make details blotchy. David didn't mention file type and size.
