But what screen color/gain did they do this with? I am not sure if those numbers make sense with my gray screen.
Correct me if I am wrong but one calibration that is correct for a white 1.0 gain screen would be wrong on another (different screen)?
Good question, and yes, nothing replaces doing the cal yourself. Not only is there the gain of the screen (and other properties of the screen), but there is also the size of the screen, light control, even shift of PJ as well as throw of PJ. Of course, there's also unit to unit variation, and maybe even bulb variations. Finally, there is personal preference to calibration as well.
Will the final cal be close to the reviewer's? Very possible. Still, a couple of years ago perhaps the very best value in 1080p PJs (Epson 1080UB) also was said to have the greatest unit to unit variation by someone who sees a LOT of projectors, sells a lot, and calibrates a lot, for many years.
Personally, I would take it off dynamic, pronto. When the bulb is brand spanking new, it's almost naturally "dynamic" anyways, but new bulb + dynamic means some white crush like your getting on your last screen shot.
Lastly, I remarked that the blacks of Iron Man were very light, though I thought it was a fun movie. I think, with my very questionable memory and subjective experiences, the best black/shadow detail I saw was in an old French black and white movie, The 400 Blows. I even asked elsewhere if BW movies just made it look that way, and a video pro (critic/contributor/curator) explained that it was because Criterion did not artificially boost contrast levels here, which allowed blacks to remain uncrushed. Wow, that was a nice tangent.
