Average gamma= 2.26
Wow, that's pretty - except for a slight cooling trend down in the darkest ranges, the RS35 is superb. The color temp averages about 6575K.
The gamma controls on the RS35 allow for detailed customization, including different gamma curves for each primary color! You can have about as much fun as you would like, customizing gamma for your screen, room conditions, personal tastes, etc.
Ultimately though, Normal is the default and averages 2.26 (ideal is 2.2) over the range. Each of the four other preset gammas - A-D, have different curves, and do noticeably different things to different ranges of the image (bright, mid, dark, etc.).
In addition there are three Custom gamma modes (1,2,3) which you can tinker with. You can start with any one of the preset gammas (Normal, A-D), copy that into a Custom, and modify from there. You can even set different gamma settings for the different primary colors (red, green, blue), or all at once with white. This is one of the more comprehensive customizable gamma modes I've encountered. (and much fun to play with). of the Preset Gammas, I tend to favor Normal C, or D.
The A setting lifts the brightness in the very darkest areas, making dark shadow detail more visible, but, by doing so, removes some of the punch on dark scenes. B setting mostly lifts brightness in the 40 to 80 IRE range. It adds punch and also makes those sunny days seem sunnier. Gamma C is much like B, but a little less push in those brighter ranges, and a little push added at the low end to bring up the very darkest shadow detail. In other words, C, is very much like a cross between A and B, and personally preferable to either. Gamma D lifts the mid-tones only slightly. It is closest to Normal, but "brightens" the mid-range just slightly.
Basically I tend to favor D over Normal, depending on the movie. C is my choice when I want to make the image more dynamic looking. B will also do that but is more "over the top" and typically "distorts" the original too much for my taste.
And of course, you can create your own, similar to any of these, with your own preferences, if you like to play.
