Biology and EM/light therapy question

Factual Questions
1

Many lights (LEDs) use different levels of RGB (red green and blue) to synthesize colors to the human eye. I’m wondering if a color produced by one of these lights is equivalent to that color produced by say, a fluorescent designed to produce just it.

Here’s a good explanation for what I’m trying to describe:

So my question is, could the RGB synthesized colors have biological effects that are different from the real ones due to the lack of certain frequencies - or the lack in continuity of frequencies within the visible spectrum?

Well first off, fluorescent lights send out a set of distinct wavelengths also. But could two different sets of stimuli for the eye that result in the same perceived colour have different effects in other ways? Certainly, but I don’t know if there are any significant examples in the human body.
