I have had digital projectors since they first came out and I can say the life span is easily 4 times better today than before.
I would also add that they roll off in contrast isn't NEARLY as bad as it used to be.
I had a Madrigal MPD1 (modified JVC) that William Phelps tweaked out. With a new bulb it measured at 250:1. 100 hours later it was less than 1/2 that. It still kicked the HELL out of my Sony 7 inch CRT and was about 10x smaller. The fan noise was LOUD!!!!
