Roy, not sure I understand below where you say "dMax stays the same" 
because in an earlier post you told me: 

"The numbers are luminosity values ie. Lab. 96.86 is paper white, 16.15 
is dMax" which indicates to me that you can change the black value and 
its not always "pure" black, 0.00. 

Again, I'm relating to a photoshop curve, where, for example, you 
changed bottom (black) end of curve to something like 86%, so darkest 
part of image would not be pure black (100%); and yes, rest of numbers 
would change intermediate points or values. 

Best, David.
