Well cooking increases the available energy for one and that is separate from digestion in the regularity sense. The raw bits which would release more calories if cooked could be akin to fiber. You also clearly have a microbiome accustomed to it for one and presumably the sources were sufficiently clean that doctors haven't found parasites or similar that cooking would address. I guess low quality means cut as opposed to "roadkill wildlife".
