If that is anywhere close to what you're seeing, your gamma is too high. Shadow details are crushed and skin tones are shifted towards lower end of color intensity. What are you using as a source? If it's an HTPC, I can tell you how to fix that.
Despite that, I'd love to have the option to have a CRT projector in my place.
I understand what you're saying, but what the shots are showing is not what's on the screen. I usually just post them the way they come out the camera. I never tweak any of my shots, but when I really get into taking them. I usually do a better job at setting up the projector and also capturing the image with the best camera settings.
I don't make that big of a deal out of it, because it's all be reproduced using a $99.00 point and shoot camera.
