I don't really understand this. Let's assume a specific profile is way
off with respect to one specific color patch on the target. Now, it
might well happen (and in fact, did happen during my testing), that a
real scene contains an object of exactly this color. As a result, this
"real scene object" will have a wrong color on the image. How does this
not make the profile a "bad" profile for color accuracy?
Because a cameras spectral sensitivites in general don't
match a human observer spectral sensitivies, metamers to
one may well not be metamers to the other. So there
can be colors that appear identical to the human observer
that appear different to the camera. No uniform color
transform can fix this!
