No, i have it calibrated mostly by eye and for confort, considering the low light i usually work in (not complete darkness, but dark).
I'll look into calibrating though, and further adjusting the palette.
Edit:calibrated (just needed to up the contrast), and i'm not really seeing what you mean. Eyeburns where? Near the higlights? The whole thing? I tried it against backgrounds with different hues and ligthness, and calibrated the palette so that it would could be seen well against bright or dark backgrounds, and the details would pop out well. (like the white snout fur could be distinguishable from the head's yellow fur).
