Well I worked on the 70″ pro model yesterday. The THX mode out of the box was not impressive. Some large dE’s with both greyscale and gamut. I did use the low local dimming feature during calibration. The 10pt greyscale either didn’t work at all or worked in very fine increments. I thought it was the former and so I did not use it. The color controls seems to work well with luminance on all colors very good. Overall, no colors over 1.5 dE. I did not find the magic button to turn off the yellow pixel. It made the green window look like lime. Gamma was about 2.2 and relatively flat.
Not impressed with this $8,500 model.
