Problem solved! I did this with i1d2+ccmx. I change Profile type to "Single
Gamma + matrix" and bam all the shadow details are there!

Is there anyway I could create a "single gamma + matrix" file for Colormunki
using the existing saved calculation data without running through the
"Calibreate & profile" process again? it's painfully slow when I use
"adaptive hires" + Black Drift Compensation for the Colormunki.
