It would seem to me that "there is no difference with appropriate light intensity settings" would be a much more publishable result? That max. brightness affects sleep is an unsurprising "common sense" result (although still worth doing research over just to verify), but I – and I think many people – genuinely don't know if there's an effect with low light settings (and/or colour temperature settings), and if there's an effect, how large that effect might be. In short: that seems a much more interesting study.
