The requirement for 'most versatile' doesn't follow in that sentence.  
You are making a logic error, or at least taking the biggest car and  
hoping it will get you there fastest.

If you want to satisfy your needs, try it for a while and see if it works.

Hmm, you pose lots of questions that are completely off-topic here.  
And jumping to weird conclusions about dropping work is just unhelpful.

I strongly disagree with that.
KDE is not a support group where lonely software goes to get more  
recognition. This community works based on choosing solutions that  
work best.  Your suggestion to not choose is therefore not helpful.

Then I'm sorry to say, your opinion is just that, one uninformed opinion.
At minimum read this;
And tell us if there is any reason to say that this product does *not*  
satisfy your needs (when the KDE stuff is finished)

There are not a lot of experts on the topic, no.  I've been doing my  
first physical monitor and scanner calibration back in 1999, on the  
Mac. (with a Barco monitor).  I've been reading many (beautifyl) books  
and I'm nowhere near an expert at all.

 From a software engineer point of view there is a good solution;  as  
I *do* have the basic information needed, and thats easy to get to for  
everyone else as well. Read the above linked page, for instance.

Basic design of system color management is that each input (scanner  
etc) and each output (monitor, printer) has to have assigned a  
personal color profile.
Applications that are capable of doing color management have to have  
access to those profiles so they can use them in combination with a  
library like lcms to do the right thing.

Colord embraces that concept and provides all we need.

Oyranos makes things ... complicated.  See;
