Cam,
My 3LCD rear pro tv has similar effects when you are at extreme angles in any direction. When sitting watching a movie, there's no problems, everything looks good, and even pretty wide angles (~45-50 degrees to a side) the TV still looks really great. Standing is pretty terrible. My tv is maybe 20-24" off the ground, perfect for watching in a seated position, but when standing up for any reason (guitar hero) the colors wash out, and sometimes even look kind of like they are a negative of whatever is displayed. It's not a major concern most of the time, and when standing, but farther away (when i'm cooking) the TV looks perfectly fine, it's just those extreme angles. does that help at all? or did i totally miss your question.
