Would not the definitive answer to this be a computer screen.

On one side you have an apple, illuminated by natural sunlight. it fills your eye with a rich texture of subtly mixed frequency's covering the whole gamut of visible and invisible light. On the other a picture of an apple composed of brutal pure frequencies only emitting at 430, 540, 570 Nm. Can you tell the difference?

That makes sense. I feel a little silly that that's not something I considered despite the article saying exactly that. I think I got caught up in the details.
