Calibration needs many options. Thats why Oyranos supports them.

Agreed. Thats why Oyranos limits its usage just to vendor profiles. All 
others are much more flexible and robust handled through all available 
and understood calibration data.

I outlined the model used in Oyranos. It needs somewhat more programming 
time as you put into whole colord. Still its is already implemented as a 
robust base for a good user experience.

Changing the gamma slider and colord can not account for this. I would not 
say this works.

This page propagates simplicity? Then colord is overly complicated. Just 
tell all people they shall use sRGB and the same to device manufacturers. 
Thats it ;-)
