Sure, you have experienced grass with more senses than just reading about it, but I do not think that this fundamentally changes anything. If I lied to you your entire life and told you that you are walking on or smelling grass while you were actually walking on moss, you would learn a similar mistake spanning several of your senses.

No, I would know moss instead of grass, and I would know it consistently. I would simply have a different label stuck on it than everyone else used.
