On the Bench
In the Natural Mode, Full On/Off CR was1374:1 and ANSI contrast was 270:1. After calibration, Full On/Off CR was 1402:1 and ANSI CR was 273:1. There was plenty of brightness, delivering full spec at 1,200 lumens.
The color temperature before calibration was "hot" (too blue). Calibration brought it closer to the ideal, but there was still deviation at either end of the IRE scale.
Before calibration, RGB analysis indicated that there was too much blue, about the right amount of green, and not enough red. After calibration, RGB was OK in the mid-IRE levels, but was still not very good at the extremes.
Gamma before (2.02) and after (1.94) calibration are shown below. The ideal is 2.25.
Here is the CIE chart. There is sufficient red and green, but not quite enough blue.
