I would guess a conservative end point recommendation has to do with two
things primarily, compression (in reproduction) of the full range painting
is capable of, and paintings being different from one another. This makes
the handling of those compressions case by case and somewhat subjective.
It is often noted that technically "accurate" reproductions of painting can
appear somewhat lifeless compared to the original. The reason is obvious,
compressions of range, scale, and depth. Since the notion all paintings can
be reproduced "accurately" is incorrect, and for the best possible aesthetic
result, a set of "enhancing" distortions compensates compression distortions
to the extent possible. A profile and conservative end point settings is
the correct starting point.
