I have not ignore the spectral sensitivity curves, I have mentioned they are
just "similar", the differences does not look bigger than the different
between Pro Image 100 and Kodak Gold 100 curves. And for the Pro Image 100
and Gold 100, the characteristic curve (density vs exposure) is also
different, while the RDP III and RAP is very similar.

In summary, the Pro image 100 and Gold 100 you compared have all three
curves different and the RDP III and RAP only has one curve shown bigger
different.
