That is a very nice looking home theater and a great job in that room!
That said, I do see some things in the design of home theaters on the forum that leave me scratching my head somewhat. This is one example. As we all know, to get the best image out of a projector/screen combo you want to minimize
the reflectivity of the room, especially the boundaries around the screen. Your room has nice deep red portions that would help do this, but you've painted the walls a bright cream (or white). Given how small your room is, this places those bright walls almost directly to the sides of the screen, so it's like placing two more projection screens on each side of your actual screen. I would find this quite distracting in itself in terms of the walls lighting up during movies, but it would also have a negative effect on your image contrast/color as well due to the reflections back to the screen. And having gone for a high quality JKP Dalite Affinity .09 screen, it implies you are concerned with optimizing image quality.
I can certainly understand such set ups when it comes to non-dedicated rooms - I myself couldn't go painting my walls really dark because my projector is in a main floor living room area. But when it comes to actual dedicated home theater rooms where you can do everything to optimize the image quality, I'm....intrigued...when I see so many moves made in the right direction, only to be somewhat sabotaged by perplexing choice (such as painting walls near the screen white).
Again, aside from that head-scratcher (to me) your home theater is a really great job done in a small space. Were you just worried painting the walls of a small room darker and that it would make it feel too claustrophobic? (I don't think it would, given the right wall color/lighting. You could have significantly darker side walls with some nice lights aimed at them, making them brighter with lights on, but non reflective once lights are out for a movie).
(I was rather amazed to see a while back in a British Home Theater magazine an article following one of the writer's home theater reno. He painted the entire room BRIGHT WHITE! For a projection set up! This, from a writer in a magazine devoted to telling people how to get the best performance out of their equipment!)
