Somewhere, people are really off track. If two different TVs are calibrated properly... then color A will be indistinguishable on either. Color B, C etc will also be indistinguishable. So whatever folks are talking about her is a bit silly. Ambient lighting conditions, screen reflections and how black the screen gets will be much more determinative. The point of calibration is not to produce pop but render color and grayscale as accurately as possible. Once you get the set within a certain tolerance of spec... the human eye can not detect the actual error. The current crop of Mits DLPs can be dialed in to around 1.0 dE errors on primary colors and near zero on secondary colors. These error levels are below the threshold of normal vision.
The DLP will have a more smooth film like appearance. Plasma will tend toward SDE (screen door effect) and rear projection DLP will tend to show some SSE (silk screen effect). The biggest drawback to picture quality on the DLPs is black level and that black areas of the screen tend to get corrupted by nearby bright areas due to light scatter. This is pretty unique to rear projection and it keeps the overall contrast ratio lower than plasma. This lower contrast can be mitigated by the use of bias lighting..
