Would you please elaborate about a practical detail in the example?
As you wrote she printed the colour target on a roll, registred the new 
media type and uploaded the resulting profile with the job ticket. That 
is profile B on her printer.

Her printer now knows two ICC profiles with following schematic tickets:
ICC Profile A {gamma=1.7 connection=wlan size=A4} // an earlier profile
ICC Profile B {gamma=2.1 connection=usb size=A4}  // the new profile

After that, she wants to print postcards on the same roll from here handy 
app. She only remembers the newly created ICC profile name (B). Thus her 
actual print ticket says something like:
Use profile B through my wlan connection and cut the roll after postcard 
height.

How does the CMS select the right calibration gamma?

It is great that you incorporate that for the designed of the standard.
