No, they aren't related at all.  The "Color|White point (%)" option controls
how much of the image clips to white.  This is what most minilabs do
when printing negative film, and setting this option to 5% or 10%
duplicates what a minilab does.

The gamma option in VueScan is equivalent to changing the
midpoint of a correction curve.
