for why the wavelength of red feels from the inside like a built-in quality of the world rather than a perception generated by a mind in response to a stimulus

That insight would be an additional layer of processing requiring energy that could be used for other things. How would such an insight increase the brain's reproductive success? We don't have insight to our outputs either, you don't intuitively understand how your muscles work in response to stimuli, which is part of the reason why it feels like we have free will and are agents in the world instead of parts of the world.

The true quality of stimuli is already lost and grossly simplified at receptor level, in the case of light the photoreceptive rod and cone cells of the retina.
