I don't follow you. There will be the same interaction, irrespective
of the dimensionality of the space (in fact there is likely
to be more since 4d luts are generally lower resolution than
3d luts), there are just more ways of a color being specified
as an input, multiplying the number of colors to adjust by a whole
dimension. Typically a high res. lut would have a 3d grid resolution
of 33, meaning it has about 36000 output colors that could
be adjusted. A high res. 4d lut will typically have a grid
resolution of 17, meaning it has about 84000 output colors that
could be adjusted, a task that is clearly at least over twice as great.
