Using CalMan v4 with an i1Profiler Pro, Carada 1.0 BW screen, I spend a good time learning the calibration process. I was initially frustrated with my findings (see earlier posts) but turned out to be a defective meter.
In terms of settings, the few surprises I bumped into are the following:
1. Lens Aperture set to zero was the only setting that got me a luminance within the acceptable range of 14-30 fL (theater room w/projector). With aperture set to zero, I get a luminance of 32 fL (bulb on normal)
2. The 6000K setting for color temperature is the closest to 65K (it gives about 6,350K). The 6500K settings gives about 6,800K.
3. The SuperWhite' setting for HDMI with the Standard color space where the easiest to work it in terms of grayscale calibration and color gamut (in a way - see below).
4. In my lighting condition, I choose a target gamma of 2.3
Since the RS45 lacks CMS, I was not able to do much with the color gamut. Only controls in my hands are the Color and Hue. I did modify the color setting slightly trying to control the off-blue but couldn't do much here since fixing the blue breaks the other primiary and secondary colors.
At the end of the exercise, I feel that I have a better picture. Numerically, my grayscale and gamma are perfect, dEs are great (<3) except for the blue. My hues slightly off. I'll try to get accustomed to these settings for few days and if not happy, go back to the drawing board. I might consider adding a Radiance if I convince myself that CMS is not "over-rated"
My settings as they stand now are as follows:
Picture Mode: Custom (started with Cinema)
Contrast = 5
Brightness = 0
Color = -1
Tint = 0
Color Temp = 6000k
Gamma: Custom (I can provide values for my custom curve but note sure it makes sense for someone else to use)
Sharpness = 0
NR = 0
Color Space = Standard
CMD = off
Lens Aperture = 0
Lamp Power = Normal
Attached are some charts for my calibration steps:

gamma-before: shows initial gamma
gamma-after: shows gamma after calibration (a custom gamma curve was edited with gamma=2.3 as the target)
grayscale.jpg: shows grayscale after calibration (calibrated the 30% and 80%
and the other values fell in correctly)
after-std.jpg: color gamut after calibration but before grayscale calibration
after-std+grayscale.jpg: color gamut after calibration but after grayscale calib.
after-std+grayscale+color5.jpg: color gamut after setting color (visually) to 5. Initial setting was 1.
