Steve - I don't think I can give you the reasons for it, but the LightJet prints I've had done are not neutral unless you work to make them that way after getting the lab's profile. Perhaps it has something to do with the paper; traditional darkroom printing paper obviously varies in tone away from neutral depending on the chemical make-up of its emulsion and the chemicals in which it is processed. In terms of the range, the d-max might be greater that what I get with UT-2 on PhotoRag, but there is compression of the lowest tones and a loss of information in the highlights earlier than there would be with inkjet printing.
