Autumn; an intriguing time for full spectrum photography

I can't wait for autumn! As opposed to using a full spectrum camera, I set a custom white balance for each color spectrum; UV, Visible, and IT. A regular full spectrum camera would instead set a custom white balance for the full spectrum in general. Therefore, I consider my full spectrum photography as more representative of what reality actually looks like, or how it should be interpreted. Do we actually know if a full spectrum camera sets an accurate white balance for each spectrum of light? That's something that I'd be compelled to figure out, although I'm just about sure that that's not the case. Let's wait and see what colors autumn brings! And maybe I can map individual UV spectrum using a full spectrum camera some day!?
