Former neuroscientist here: it's just you. You may not respond sufficiently/differently to cutting out blue wavelengths, but for many people, it helps. It's not pseudo-science, and I'm not even sure why you said that. There's quite a bit of literature at this point demonstrating that the suprachiasmatic nucleus (the primary timekeeper of the body) is heavily entrained by specialized retinal ganglion cells (ipRGCs), that are most sensitive to blue wavelengths.
