Eric Stevensread what andrew rodney wrote. it uses lab internally for a reference. it does *not* convert from lab on the fly, as that would be slower.
I think the key point is whether or not the data is ever stored in RGB. Everything I have read suggests the data is stored in device-independent form (which RGB is not) with various suggestions as to it being stored in XYZ or Lab. The book I quoted has it that the Photoshop ACE (Adobe Color Engine) uses Lab. I don't know whether the alternative ICM (Windows) or Colorsync (Apple) color engines do the same thing.
