The only way to really tell is to look at the commands going to the scanner. I don't use the Nikon software so I don't know for 100% certainty if the scanner operation changes with gain. If you can view the raw scan and see no difference, that would be a good clue. On the Artixscan, the only change I found was the "long pass"
Given the illumination scheme used by Nikon, it may be possible that the LED intensity is changed as you adjust gain. I think for a CCFT, this is less likely.
