There is still a small dip in color temperature below 50K (to 20K), which would tend to account for the slightly extra red in skin tones, especially those where the skin tones are not brightly lit. Overall, this is an excellent grayscale result.
Gamma: The film gamma setting is the one that should be ideal, but it is not. It measures an unusually high 2.56 (optimum is 2.2). As such, using the film gamma setting will tend to make mid brightness objects a too dark. Sunny scenes just lack that feeling of a bright sunny day. Switching to the Video gamma drops the gamma to 2.04, which means it's a bit too bright in the mid-range instead. I've watched with both, and with a number of movies I just couldn't handle the Film. Overall, I preferred the Video setting, although neither is ideal.
