That's the story I was told by the guy in charge of deploying these. He said it was a design defect and they would be replaced. But that was over a year ago and we still see this? And it's widespread. The defect story doesn't make sense to me anymore.
With you on this one. I deal with commercial lighting and this makes the most sense. When I started about 10 years ago the majority of lights were still fluorescent and incandescent. Led was just starting to take off. Now everything is led. We are now seeing the problems that can occur with led. Warranties only being 2-10 years depending on the manufacturer. I bet Warranty on lights are over and no one wants to pay for a replacement.
One possible explanation is that the blue/purple is a manufacturing defect. I have a background in electrical engineering and this is believable.

I had a TV that turned blue. I had to replace the LED backlight.
The yelllow phosphor layer that downconverts the blue-violet LED light to yellow light must have degraded.
