I suggest you educate yourself by reading articles written by ISF (Imaging Science Foundation), SMPTE (Society of Motion Picture Television Engineers) and others.
No two televisions will be the same. Under the current state of the art, the best way to achieve a color television image which comes close to reference industry standards is to have a professional ISF trained technician come to your home. They use expensive tools which the average person can not afford. Calibration disks only approximate to an individual eye which is not trained to know what the correct colors, gamma, grey scale, etc; should look like. You can get get good results but not as good as a professional calibration. You need scientific instruments to achieve the best result. I could post my calibration charts, but you would see they are different from others posted on this thread because although the same model they have variance during manufacture. The best ISF calibrators use the same standards to calibrate using a propitiatory computer program to achieve the final result.
If you are happy with your set, fine. Once you discover the benefits of calibration, how blacks are not crushed, how shadow detail improves, how retina burning, over saturated colors are toned down, you will appreciate professional calibration. It's money well spent.
