OK - please point to it, and describe what it does.

This remains pure baloney. The LCD is, in order to get maximum efficiency
with a given color gamut (esp. in the more recent "wide-gamut"
products), needs to have a CCFL (or other light source) whose
emission spectrum provides a reasonable match to the color
filters (you remember, those little patches of colored photoresist
on the "top" substrate - basically, the side of the panel toward the
viewer?). But that's done through the selection of CCFL phosphors.
There is no magic "correction layer" between the backlight and the
panel to do this.

I suspect that by "accurate" you mean one that shows this
supposed "correction filter," but since no such thing exists in
any mainstream LCD, it would be rather difficult to produce a
diagram that shows it.
