I couldn’t find the post, but there was a more recent post (I think it reached the hacker news front page) about how just about every LED bulb has significant blue emissions.

Every "white" light has blue emissions (blue is, after all, part of white). Blue is visible, the LED blue emissions for a 2700K bulb are no more or less than the emissions from an incandescent.
