Hi,
How are you determining the "real" media white ?
The single white patch in the data set has a value of Lab 85.059164 -8.124163
-0.490875
using D50 illuminant and the 1931 2 degree observer,
while the smoothed profile white point is 86.311126 -8.360063 -0.733073,
a difference of 1.296812 delta E. This seems perfectly normal.
Graeme Gill.
