Depends on the Calibrator. I have two plasmas one done by Best Buy(he did a respectable job) and one done by Chad_b(incredible outcome). The Best Buy calibrators are constrained by time and do not ask near as many questions etc. Chad spent over 3 hours on my set and was more than willing to tweak anything until I was completely satisfied. So imo Best Buy result can not compare to what a highly skilled calibrator can do but still worth the investment if you get one that is dedicated to producing a good outcome.
