You asserted that the color filter was a layer between the backlight
and the LCD panel (cell) proper; your exact words were:

"I've split apart many LCD panels and I've found the color
correction filters in between."

Please identify the "color correction filters" in any of the process
or panel/module diagrams shown.

Nope. There are diffusing layers, and there very often are
what are known as "brightness enhancement" films, which basically
serve to redirect the light forward. There's then a polarizing film
which is bonded to the "lower" substrate of the panel itself. Please
find me a "color corrective" filter in any of that. What is it you think
that this mythical "color corrective" filter DOES, exactly?
