I don't usually trust CNET settings but if those actually are accurate then the 640 is not the same as the 632 regarding calibration.
The obvious variances with the CNET settings are...
Contrast = 30 (could have some color shift to it at the upper IRE range)
Brightness = +2 (this is higher than the 632 calibrates at with either 0 or +1)
Red Hue = -4 (this needs to be pushed + on the 632 to correct flesh tones)
Red Saturation = +3 (this + can cause issues on the 632 which has an issue with Red)
Color Temp = Low (the 632's greyscale is not that accurate out of the box with any preset, Low is the most accurate OotB-632 but requires more adjustment than the CNET settings show)
120 Hz = High (no way, nuf said
Gamma = +2 (on the 632 this would result with a roughly 1.6 to 1.8 gamma or possibly worse)
Red HUE should be shifted + on the 632 but you can try to lower the setting a little and see if that helps your skin tones (we have evidence of set to set variables within the 632's but there are likely even more going from a 632 to a 640).
Best of luck on the 640 (I dig the new top bezel, like it better than the 632).
