That's right - the monitor has its own framebuffer and output LUTs which
it can use to apply various corrections. Generally, apart from the
backlight brightness which can be adjusted without impacting the panel's
performance, you want to touch these controls as little as possible. If
you have colour-temperature controls it's worthwhile using them to
achieve a neutral white-point of the colour-temperature you require, but
other than that, leave things set to the factory defaults. Most
notably, you don't want to touch any form of contrast control.

I think those monitors just use LEDs instead of CCFLs to provide the
backlight, but other than that the principles are the same. I'm not
100% sure though.
All the best,
