If the display is calibrated correctly and you are using a profile correctly you can assume the colour is correctly displayed, or more precisely, that it is displayed as accurately as the system can manage. But without dragging out a lot of more expensive laboratory equipment to double check the calibration and profile are effective, there is nothing you can do.

Also note that human vision ( eye + brain ) is very personal. We all see colour slightly ( or even very ) differently, so "right" is also not a very easy thing to define outside of a very narrow scientific context.

In the context of producing an image for human consumption I would also say that I aim for pleasing colour not accurate colour. Accurate colour portraits are often not well received by their subjects, in my experience. Colour balance is often used to enhance the emotional response of the viewer.

Put it this way : do you photograph for your own technical gratification or for the viewer's gratification ? Is it about emotional content of the shot or technical precision ? I'm not saying one is right or one is wrong - that's a personal thing. I am suggesting a different viewpoint from a purely technical one.
