Following Drew Hess mentioning:

.. I asked if parameterized transforms will be the way within OpenEXR for 
exchanging device characteristics.

Parameterized form makes me thinking about stuctures, logical 
fillable by ICC profile structures and vice versa, Such as describing 
colour primaries, matrices , gamma values, or using parametric curves as 
described by section 6.5.14 of the ICC spec ...
