One apparent misconception is relating between relative Y values with
absolute luminance level - there is no such relation. Easiest way to
find out the truth is to take a spectral measure of the patch and of the
white point of the monitor with I1 and convert it to XYZ; but you have
to decide first relative to which illuminant you're going to calculate
it - the actual monitor's or one of the standards - D50 etc. If you need
the values relative to your monitor's white point, so since you've
measured the whitepoint itself then the DTP92 readings under colorshop
are closer to the real thing since the Y is suppose to be 100...
