Oyranos is optional. The configurations are planed to be parseable JSON.
It is up to de elopers to find value in it, e.g. it's multi monitor colour correction. 
But that might become more interesting once Qt/KDE widgets are colour managed.

Btw. Oyranos is in parts a wrapper around lcms. It does not implement 
ICC colour calulations like lcms, qcms, ArgyllCMS or SampleICC.

They use colord. But that itself does no colour correction at all, just configuration.
Gnome apps use lcms, like in Inkscape or Gimp.
