I almost hate to step into this, but I will before I get another cup of coffee and think better of it.
I like hard data, too, and I read the paper linked above. My take is the only attribute that would seem to apply is the contrast ratio (from a video standpoint, anyway). I don't think the cross reflectance would be an issue in most of the theaters designed here, and even so, the argument could be made that if you're going with a cheaper screen, the cost of admission is black walls and ceiling. This now boils down to whether the newer woven screens have improved on their ability to reflect light back to the viewer through a tighter weave, better coatings, secret sauce, etc.
It doesn't seem like there is enough analytical data on the new screens to make a call there. I don't doubt that a perforated screen is brighter. It just makes sense for it to be. However, considering the cost of admission for a "good" woven screen. I think it may very well fall into the buy it now and upgrade later category. In this hobby, we don't think much about upgrading a several thousand dollar PJ. I think buying a $300, $400, or even $500 woven screen for now, and upgrading later to a perforated screen seems downright sane in comparison to upgrading a PJ.
Just my $0.02, and it's worth what you paid
