But those are ICCv4 specs while Spectraview profile is only v2.1!
Former ICC v2 specs do not define this topic explicitly. AFAIK the first "hint" appeared in the Specification ICC.1:2001-04 (Profile Version 2.4.0): "The mediaWhitePointTag contains CIE 1931 XYZ colorimetry of the white point of the actual medium. If the viewer completely adapts to the white point of the medium (as is often the case with monitors) this tag should be set to Xi, Yi, Zi (the PCS white point)". This Phrase recurs literally in the Specification ICC.1:2001-12 File Format for Color Profiles (Version 4.0.0)
