That's a very good question. Ideally (I guess) the 3D fitting, as I suppose
(if I understand correctly) there's more flexibility to adapt to device and
illuminant distortions in colour space. But if it actually doesn't really
matter, either way would be fine. I just know that my application will need
to work properly in rather uncontrolled environments (regarding
illumination).
Are there any comparisons or studies on the benefits of either approach
available already?
The ICC profile LUT format uses both. Per channel input curves,
then multi-dimenstional LUT then per channel output curves.
The V4 format adds another set of per channel curves and a matrix.
So ideally a representation of a device response or color transform
would make optimal use of all these mechanisms.
