I don't know how you achieve this scan, it seem better than my experience
especially with Gold 400, are you sure it is Gold 400 or Royal Gold 400? On
the other hand I don't need to print a 20x30" print to see the grain, it is
very obvious even at 5x7 print. Something on the monitor doesn't mean it
will be the same on print, just like you see a very good 1024x760 pixel
picture on monitor, if you print at 8x10 (monitor size) obviously it will
not look as good.

I also have tried Neutral balance before, if you said you are going to make
final adjustment on Photoshop that is fine, it means the contrast or
even color is not right so you need to make the adjustment. A gray
card will help a lot but it doesn't solve all the problem, it only has "one"
calibration point and it cannot take care of the whole color spectrum.

Here below two parallel scans of different negatives, as can be seen all of
them has clearly different film base, subtle or not depends on personal
standard.

With a good equipment, scanning slide can be easier, it has much less
hesitate than scanning negative.
