The lens memory isn't flawless as other said. Sometimes it's off from the mark, but most of the time it's fine. Plus it has nothing to do with the color calibration as it only zoom in and out the lens for the screen, color accuracy will stay the same. E.g. a 150,150,150 red will always stay 150,150,150 regardless you zoom in or out.I had Tom Huffman from ChromaPure to calibrate the projector for me.
