Yup, nailed it.
At the end of the day though, all I know is what my fingertips and ears tell me, and those two admittedly subjective data collectors tell me the wood and construction make a difference. Even if its just the way the guitar feels due to different wood/design that's enough because it will make you play differently, and the sound will differ. These things don't play themselves so the human element is not a variable that should be factored out IMO.
Right on in your description.
