>They are saying that, and most real world LED lighting uses very cheap diodes, like, 99.9999% of them, which create very poor colour compared with incandescent bulbs, which create perfect colour representation.
Have you actually read the study? It's about infrared and has nothing to do with color rendering and visible spectrum. They're vaguely speculating about some mitochondrial mechanism of action not related to vision at all.
That's the interesting thing about this study. A lot of people here are speculating around explanations connected to metamerism, but the control (Figs 7 and 9) partly rules that out.
