I would not say that a typical calibrator will know about the CCA function, but a properly qualified calibrator will. It is important to interview your calibrator before hiring a specific one. We have written an article on this located here:http://www.avical.com/articles/hirin...echnician.html
As for DVE... The tutorial of the program and the patterns contained within will require you to use the color filters in order to achieve accurate color decoding. If you had access to a spectal based colorimeter or a spectroradiometer you could measure the various levels to set this up properly, but it is much more efficient, and cost effective, to use the filters.
No, the CCA will not turn on automatically when you turn on/off the display. You would need to enter the service menu, disable CCA, exit, make the adjustment, write down your numbers, enter the service menu, turn CCA back on, exit and plug your numbers back in.
