There is a thread dedicated to the blue light topic that would be a better place for a detailed continuation of this tangent.
As a couple brief comments, though: I second djozz’s observation that the spike shown is very typical. For example, in the top part of image here is a spectrum of a 4500K Nichia 219B (from Maukka’s Fireflies ROT66 review) of the same color temperature. It’s very similar in the location and relative scale of the peaks and valleys:

I’ll leave off my other thoughts on the topic, and simply note that based on the research I’ve read: if in doubt, there’s certainly no harm in erring towards lower light levels as the first priority, lower color temperatures as the next priority, and high CRI as a final priority to reduce blue light exposure. However, I have not seen research that indicates the typical narrow spike is worse than the more spectrally distributed but similar total energy of blue emission in an idealized black body.
