Well, I got no reply after a day, so my curiosity got the better of me and I installed SpectraViewII v1.1 after wiping out v1.0.4. No noticeable downside so far, but a couple of observations.
1) The interface is less elegant from a graphical standpoint, but easier to use as it has all of the options laid out more clearly, with descriptions of each option. Over all, an improvement.
2) The "Photography" option for the calibration target now specifies a recommended 140 cd/m2 rather than 120 in the original version. (A bow to Andrew Rodney's statements on minimum luminosity settings?)
3) For calibration of primary colors, to the options of "use Colorimeter" and "Factory Defaults" is added "Automatic Selection." I don't know if it makes a smart decision or just reads the version of the colorimeter and uses a LUT, but with my EyeOne Display v.2, I used the Automatic option.
Another question comes up: I seem to get very decent results using the Factory Defaults for determining the Primary Color values (which I assume will be selected by the Auto setting anyway). Would there be much of an advantage to ugrading the colorimeter to the Wide Gamut one from NEC? I am not even sure whether NEC sells it separately from the software, and I already have the software.
