Yep, that must look great. All you need is the martial theme from "Thunderbirds" as the screen comes down
I definitely don't need higher gain for image brightness in a dark room (the Sanyo is rated 1000 lumens at full power, 300-ish at best PQ), it's just that the viewing area is wide open on two sides, one of them to sunsets, so sometimes the ambient light level is going to be pretty high.
Then again, I guess most of the movie watching will be in those long cold winters when it gets dark at 4:30 and I get home from work at 7:30
