Factory Black paint mismatch

[gdmn852]

Hello, this is basically a hard question to answer, as few cars still have original paint, but would there have been a slight color difference between the Black enamel fenders and black Lacquer finished bodies? The gloss would probably be different, lacquer dulled down with out polishing.And has anyone building up a restoration for show replicated a possible difference?One reason I asked this is a friend of mine had a nice original 1939 Oldsmobile, that must have be damaged rear fender and deck lid showing repair work,and under some lighting conditions the repair area was more of a gray shade than rest of body . Could be due to factory paint and aftermarket repair. Thank you.
