Here's a recent take: https://www.quantamagazine.org/why-are-plants-green-to-reduc...

TLDR: Plants are running an energy-harvesting system that can only respond so quickly to changes in light input. Making use of green would cause variance to be large enough that the gains would not offset the losses. So, avoid green and have lower variance --> higher energy capture on average.

That would be easy to test, I suppose.

In fact, perhaps we're already doing so by letting plants live in our offices with 60Hz flicker, and perhaps higher frequency flicker caused by LEDs and PWMs.

In short, I'm not buying this theory just yet.
