The contrast argument is not a standard option, so it depends on the
backend.
Gamma curve adjustment is often better done in the scanner, simply
because the scanner often has a deeper A/D converter than the 8 bits
per channel of the data you get from it. Therefore performing the
adjustment in the scanner gives better results.
On a slow computer, you can also save time by having the scanner do
the adjustment.
