But maybe some of the other differences between models that you mention help explain things.
I know you are a smart guy and I love your room btw, it's ingenius and I am forever amazed by it for real, I went to your thread so many times just to enjoy what you accomplished (and to be jealous).
I think your perspective is very valid, so not disagreeing, I really haven't A/B'd those two projectors enough to know. I will say this from my own A/B experiences though...
Calibrate, re-calibrate, calibrate again, this is so true when A/B'n two JVC's, you'll need to spend a good bit of time getting them to look identical from gamma and color, it won't be easy but you can do it.
Some projectors with certain content need many many hours to A/B. For instance, there are movies that favor less sharp projectors and will show less image noise for that reason. I've noticed some of the JVC's hide some of that noise a little better than newer JVC's, but they are not as sharp on average either. Let me say though I'll push again the calibration issue, I've seen multiple RS-20's in controlled setups and my friend owned one. It would be interesting if you could or a calibrator could A/B them and keep re-calibrating to get them to look as close as possible and watch both for hundreds of hours going back and forth in the SAME room. I did this with DLP vs. LCOS.
Everything has advantages / disadvantages unfortunately. There are even movies where e-shift should be turned off (sorry zombie), there are movies where sharpness should be increased, lowered, gamma changed, etc...
Oh such is life, I wish every movie used cameras and filming techniques as good as the best ones do, then it would all be easier.
