Damn you stole my question ! And that might be related to what Kai-Uwe 
described here [1] . RGB -> XYZ -> RGB doesn't seem to be the identity this 
might be a problem.

And beside, I also think that this only a variation of the "quick and dirty 
lab32f". While RGB32f -> RGB16f can be done with a shortcut, RGB32f -> 
XYZ32f -> RGB16f, will be at best an increase of computation time, at worse 
we will get a variation of the effects from [1].
