This reminds me of a video [1] going over the use of structural color photography, where theoretically what you see in real life is what you get in your final image. It cover some of the same topics, but goes more in depth about the process of structural color and some animal examples, like the butterfly mentioned in the article. If you have an interest in chemistry or film photography it is a great watch! This process was also, to my knowledge, the stepping stone for holograms, which we can now see structural colors everyday on IDs and licenses.
