We don't have our C300PL yet (though we keep waiting), so I can't tell you firsthand...
BUT... I will say the ability to do that is one of the things that was touted in the pre-release teaser videos for the camera... that the monitoring mode choice doesn't not necessarily have to be a what-you-see-is-what-you-get type of thing... and that you
can goose up that output when shooting in one of the flatter modes just to avoid exactly what you are talking about... people viewing on location thinking they are getting a bad image.
But
how to do it, I couldn't say... but dig through the manual, as you are
supposed to be able to. Or at least at one time Canon said you would.
