Since BOC is under 1.0 gain, and usually Mfg so as to be uniformly coated, when one also manages to stretch it evenly and tightly, all the aforementioned attributes you state are there to enjoy. You at least seem to be at that point, and you bet, people have been heralding the attributes of BOC Screens since the first one went up. However when comparing BOC to other applications, quite often one still sees the advantages in having a Screen with at least unity gain, if not indeed a surface that enhances perceived contrast
However, when looking at your thread's title:Blackout Cloth + SilverScreen + Ambient Light Controlled + Epson 8350 Question
....one would surmise that some degree of ambient light performance is desired, and that you have in the least recognized that a Gray surface is going to provide that. (...like the HCCV screen did, but along with other detrimental aspects as well...)
Understand that it's those very undesirable aspects that exist with many Mfg Screens, as well as with some very basic DIY solutions, that drives the effort to make DIY Screens that are not just effective challenges to Mfg Screens, but that also exceed the performance expectations of those who aspire to have something better than they ever though possible.
BOC is Good....but it's simply that...Good. It can be made better.
Here are the facts;
The 8350 can use some "screen" assist...even in a totally dark room, with presenting the most absolutely best Contrast possible. A Gray can get'ter dun. I know......I've been there and done that a few times myself.
A Neutral Gray of the correct shade, when applied to a surface correctly, will often provide an even smoother image than BOC. In every instance? No...but that would be 99% "builder related".
If one employs no reflective additives to increase gain (...something you seem to not need nor want....) then it's universally accepted that a light Gray surface has the ability to create the proverbial "Looking through an Open window" effect. If that is accomplished and both a perceived increase in Black level rendition as well as some ambient light tolerance is added into the equation, then it should be easy to ascertain what you have to gain by painting the BOC.
