Unlike most TVs, the C9’s peak brightness was measured with the pre-calibration settings, because of an oddity with the 100% window’s brightness. It turns out that when the saturation of the white point is very high, the 100% window’s brightness drops considerably due to ABL. This occurred with our pre-calibration settings, resulting in a brightness of 141 cd/m², but not with our calibrated settings (240 cd/m²), because our calibration brought down the white point. When using our pre-calibration settings with Contrast set to 90 you will experience this issue; reducing the Contrast to 80 avoids the issue, resulting in a 100% window brightness of 246 cd/m², at the cost of lower brightness in other scenes.
