It depends on the scanner. I scan Tri-x and HP5+ 5x7 negs on a Umax 
Powerlook III using one of the color neg. options and the result is 
three very different channels. It is somehow related to the orange 
mask on color neg. film because I get a different result using the 
Kodak neg. choice or the Agfa neg. etc. choice.

I don't know if other scanners work this way or not but, for me, 
there is different information in each channel.
