It certainly does address your point, you may not understand why though.
There are not any other dimensions than I stated (positional and value) to
the data you get from a digital camera.

Of course interpolation produces them how is that different than "the
addition of new data points"?  The definition of interpolation REQUIRES that
additional data points be "produced" or, more accurately, "created".

You are NOT inserting any new data points.  The 6M points are already there.
You are only changing their value.  Simple as that.

Interpolation is an algorithm, and as such, the derivation of color
information does not have to be done with interpolation.  Good, bad, or
indifferent.
