Unless the original scene showed additional details in that gradient
that cannot be simulated by any form of interpolation.

In terms of chrominance, yes.  In terms of spatial resolution, no.

They have everything to do with it.  That's why offset printing never
looks like a chemical print, and that's why chemical prints never look
like monitor displays, and that's why monitor displays never look like
projected slides.

Yes, there is.  They remove fully 2/3 of the color information from the
image.

Now you've graduated from near personal attacks to actual personal
attacks.  I take it that you've run out of arguments in support of your
stated position?  I still have plenty of data and logic on my side.
