each lamp has it's own characteristics for how it's going to perform. It shouldn't be a drastic difference, but I've seen measurable differences when swapping lamps on my JVC. usually it's just the gray scale that needs adjusting.
unfortunately you can't assume that once the replacement lamp gets to the same hours as the previous calibration (with previous lamp) that it will be the same. However, the difference could be so small that it's not noticed by the eye.
The Sony looks good out of the box, I didn't bother calibrating it right away. I just reached 100 hours on my HW30 and will be calibrating it in the next 2 weeks just to see where it's at and make some corrections.
