I could not think about a good reason why this diode should die before doomsday. It has no mechanical wear, no moving parts. You are just juggling electrons between energy states what does not seem to wear them off in the last 13 Billion years either.
The only thing that can happen is a slow destruction of the crystal structure, either chemically or thermally. Keeping the chip away from aggressive chemicals and at a reasonable temperature could provide a veeeery long life. I suspect that the power supply is the one to break first. Like with other LED driven light, it‘s usually the other electronics that is failing, not the diode itself.
