In addition: are the readable target measurement numbers at the top in 
the created ICC file actually used when the profile is active in the 
printing workflow or are they just there for documentation? In other 
words can I change them there for the reason described above or will 
there not be a difference in printing after the change and the profile 
has unreadable data that actually does the job?
