1.49 to 1.5, saturation on post-processing tab having no effect

Hi,
is there a known bug or setting that would cause the saturation value in the GI post processing tab to be ignored on a scene created with Vray 1.49? We’ve just fired up 1.5 SP2 however the saturation appears to not be looked at.

Cheers
