I am saying that several people that were closer to the screens than me said the differences between the Sony and JVC were not dramatic. You can ask Craig Peer his opinion as he owns both a Sony and JVC.I'm not following you. Are you saying that the JVC imperfections were highly visible when content was displayed because you "heard" that was the case? But then in the same sentence you say that the JVC wasn't calibrated. Are you now defending the JVC and questioning Sony? And finally, you say you left because the projectors were "so far off." But the point of the Sony comparison was resolution, not color accuracy in this specific demo.
All of which misses the point which is that it was Sony's shootout, not JVCs, yet it underscored that when you evaluate only how content is presented with the naked eye, the basic JVC is an incredibly, incredibly good value. Up against a much more expensive projector, it held its own.
I left, because the Sony guy made it sound like they calibrated all of the projectors. It wasn't a passing statement either. Read this thread.
