Why 2 degree observer measurements for ICC profiles?

Hi list members. Hoping some color science folk out there on the list could help answer a question I have.

From Konica Minoltas web page titled “Understanding standard observers in color measurement” “CIE standard observers help correlate instrumental color measurements to human visual assessments. The 1964 10 Degree Supplementary Standard Observer is considered to be more representative of how the human eye perceives color.”

So why do ICC profiles, for print production, still use 2degree observer measurements instead of 10 degree observer measurements? Given that the 10 degree observer “is considered to be more representative of how the human eye perceives color. (me: Than 2 degree observer)” Thanks Peter
