No appearance difference between water and oil finishes?

Q: I have 25 year old red oak floors that I want refinished with a water-based poly. From what I’ve seen in showrooms, I like the natural look of red oak with a water based application versus the yellowish pigment of oil (current finish). One of the contractors claims because of the age of the oak there will be no appearance difference between using water or oil.

Do you agree with this? Everything I read seems to disagree.

A: The floor will be lighter with a water borne than a solvent or oil based finish.
