What wonders me is a non Y==1.0 media whitepoint tag in your profile, even if version 2.2.0 compatible. Normaly it is scaled for displays. 
I had expected such in the luminance tag, which is not present.


In order for absolute colorimetric to return the instrument readings,
the white point tag is the white point of the display. Since there
is no 100% reference (no perfect diffuser), it has to be
the absolute white in CD/M^2.
