Well accurate means accurate. Warts and all.

Who wants to listen to warts? A painting can never be accurate to an
original scene, and in many cases the original scene may not exist. Do
we criticise the painting for not being accurate, or do we enjoy it's
euphonic beauty?

This analogy is not appropriate to the issue under discussion. A
painting is an original since, in many cases, there is no original
scene for reference. A more apt analogy would be to ask if a
reproduction of the painting should be accurate or pleasing. I leave
you to to draw your own conclusion.

Kalman is quite correct in saying that the analogy is flawed.
Let's take the corrected analogy. Let's say you buy a
REPRODUCTION of a da Vinci painting that has a slight cyan cast
to it. It can be corrected by looking through an equivalent red
filter. So, you now have your eyeglasses permanently colored
red. Your new eyeglasses now result in a "pleasing looking" da
Vinci.

Great, so now you go out and get a reproduction of a Rembrandt
that does NOT have the same cyan cast. With your eyeglasses, the
same red cast is applied and now it has a red cast. Is it now
"pleasing looking?" No, not is, by your definition, "pleasing"
is "looks like the original. Now, EVERYTHING will have the same
red cast, whether it needs it or not.

Now, if you like red, fine. But to apply the SAME medicine to
EVERY painting doesn't make sense if only a few of the paintings
suffer from the same disease.

Gee, one might suggest the use of tunable color filters to
adjust individually for the differing errors in each. That means
that not only can you adjust to get close to the original, you
can even adjust to give any deviation from that original that
you want, just as along as it is "pleasing looking" to you by
whatever definition suits YOU.
