Digital BW, The Print

I just printed two of the same image, one on Matte paper with the QTR 
Matte curve; and another one on the same sheet of Matte paper with the 
QTR Glossy curve. The matte curve was created for the matte paper that 
was used for the printing (H'muhle Photo Matte); and the glossy curve 
was created for Epson Glossy Photo Paper. But for the Glossy curved 
image being slightly lighter in the upper values, they are so similar 
that viewed separately; they look identical. It's that close! Has 
anyone any idea why they are that close in appearance? If the printed 
images are going to be that much alike, why create different curves 
for matte and glossy paper?
