I've been calibrating my projectors for a few years now. It's WELL worth it. I recently moved to Chromapure and the Diplay 3 Pro meter. I was using Calman and an i1Pro meter before and find the new combo much more user friendly - even a caveman can do it easy....

Scan through the FAQ, user manual and tips on the web sight so see it it's something you want to get into. I bit of a learning curve, but pretty simple really. You buy the combo for about what a calibrator would charge you. But if you pay someone to do this, the cal will drift as the bulb ages, requiring a re-fresh from time to time, so you are money ahead doing it yourself.

Either that or live with what you have and don't dwell on it.
