I think a lot has to do with both luck and power quality as well.

When I got a new apartment ~10 years ago I filled it with LED bulbs. Mostly Philips hue, but also some generic stuff on Lutron controls. Had 0 failures for 7-8 years.

One summer we had weeks of power issues on my block. Transformer blew out 2-3 times and we had no power/low voltage/no power/restoration state multiple times. At this point 5-10% of my hue bulbs were fried. Pretty randomly since a bunch were in the same fixture and only a few of them died.

Its possible the hues died more than the generics since they are constantly "on" rather than behind a switch, so they experienced all of those voltage states directly.
