Someone that is recognized by THX as a video calibrator has to pass a much more stringent evaluation period before they are listed on the company's website as a calibrator. Nor is there any monitoring and/or process to make sure an individual is current with their gear or ever-evolving skill set. Doesn't mean your skills are worth a lick. Once you sit through the 2 day class and pass an open book test you are considered an ISF calibrator. There is no such thing as ISF- certified calibrators. You can be at 6500K and green can be wrong.

D65, found on an X/Y chart is the correct value. To clarify a few things I have read thus far,Ħ500K isn't quite the correct desired color temperature. Even then, you have to tweak them a little bit, particularly in black level, to get them right. THX has been more successful at getting 6500 degrees, 30fL brightness, proper white points, and reasonable color balance implemented on certain high-end sets, like the upper-echelon Panasonic plasmas. Joe Kane got a few manufacturers (I think Samsung was one of them) to follow his suggested settings, but for whatever reason, the affiliation did not last. We argued and argued and argued that 'but there's a known standard! Just have a preset that gets it in the ballpark of SMPTE RP-166!' But they would not listen.
