Dalite Cinemavision High Contrast screen with Hitachi 5500

Has anyone seen the Hitachi 5500 on a Dalite Cinemavision High Contrast screen ? I had ordered the regular Cinemavision screen (1.3 gain) but they sent me the high contrast version (1.1 gain, 133", 16:9) by mistake. I have the small samples that Dalite sent me, but they are not large enough to determine the difference.

I might keep it to get the blacks a bit darker, but I was just wondering, before I open up the box and installed it.

BTW, the same message is posted in the digital projectors section, hope thats OK.
