There is no real metallic content in Silver Fire. Mica Flakes are more akin to stone....sort of like Feldspar and / or Quartz Crystals. And as far as I know the JVC units do not employ Passive 3D engines.
Only LG did so of the last 3-4 years, and it pretty much fizzled out due to lack of screen availability. Certainly their twin Light Engine PJ was a real torch....but it also was expensive @ $12K
The real reason a screen with polarized Light retention can be an advantage to a system that uses Shutter Glasses is that the metallic content usually is accompanied by significant gain. Barring that, some people manage to match of the angle of incidence of the Screens semi-polarized reflection with specific glasses that are tuned so as to retain brightness through the shutter lenses.
About the time the Thread you liked to was authored, I was in England creating some 200"+ Polarized Screens for SKY. Did 'em up really well to...but the metallic infused paint was extremely toxic and flammable, and the LG cost a bundle, so the project stalled.
Nowadays, it's all about Gain...more than chasing Polarized Light beams. When Passive was producing a better image, and Active Glasses were taking a bad health rap, there was modest intrest...but much of that revolved around Gamers with dual PJs and Circular Polarity Filters they could fine tune.
Dem days are gone now...because a bunch of PJs that do active 3D come in at 2400 to 3000 lumen output in 3D Mode.
