Now, separate comments on the calibration:

The calibration did an excellent job of fixing the out-of-the-box errors, most of which were probably due to normal factory setup to make the set look like the most different searchlight on the sales floor.

As you mention, the initial factory settings usually have things maxed out, such that highlights tend to be clipped or at least compressed, so that white clothing loses detail. The adjustment to match the rec. 709 gamma curve fixes this.

Also, the calibration countered the extreme blue factory setting, which makes whites bluer and therefore appear brighter, but makes creating good flesh tones a nightmare.

Finally, the before and after primary and secondary color aim points show that the extended gamut was reduced to exactly match the broadcast rec 709 colors. The one good thing about the extended gamut of this set is that it can be reduced to exactly rec 709. If a TV natively has a smaller gamut than rec 709, nothing can be done to extend it to the correct gamut. Most sets these days approximate rec 709, but maybe not exactly.

Indeed. We bought Joe Kane's Video Essential Blu-ray Disc. There is the couple in the resteraunt scene and prior to calibration, her blazer was so blown up and over saturated that all detail was lost.

This image is taken from a Sharp 2005 65 inch set, post calibration. We shot this from an extreme angle in the viewing room to demonstrate the wide viewing angle which was a favorite topic of the day. The set in this thread is a 2012 70 inch Sharp Quatron with full array LED LCD.
