In fact the idea of light frequency restriction is dying a death in LED grow lights, sun-like full spectrum with deep red and UV ranges have proven to be superior to specific ranges (blurple). Light being a bottleneck isn't very meaningful as plant growth is adjusted by a bunch of levers, e.g. increase respiration and nutrients and more light energy can be utilized - obviously there's limiting factors in plant biology.
