Sorry yes, thats exactly what I meant in my last sentence. Referencing the current latest version (4.2) is the correct response. No Idea why I typed 3.4, sorry for the confusion.

version 2 and version 4 ICC profiles are different, and a v.2 processor cannot read v.4 profiles at all. The ICC specification 3.x still defines version 2 profiles. The specification from 4.x onwards defines both v.2 and v.4 profiles.
