no it doesn't
>artifacting on the logo?it's simply the remnants of the very last specs of emulsion where the scanner has enough power to shine through and get usable data
(this is called density and the Konica Minolta DiMAGE Scan Dual IV AF-3200 has a very nice measured rating of 4.8 same as the famed Nikon LS-9000 ED)

https://www.filmscanner.info/Dichte.htmlthe best possible way to scan anything is to scan the maximal possible range the scanner can do
save it into a lossless format (be it a tiff or dng or png or whatever lossless compression format the scanning software supports)
then edit in a program of your choice (adjust exposure and black point)
for a colour film there is a slightly more complicated workflow as you have to compensate for the colour of the film base but the above is perfectly fine for a black and white film
