How is it possible to determine if an existing floor is "red oak" or
"white oak" without removing or sanding any boards?

If you have any registers set into the floor (e.g., for forced-air
heat and/or cold-air returns) you might lift one and see if
you can spot some unfinished wood. Or if there's
a transition to another type of flooring, poke around there
and see what you can. Or if your flooring goes into a closet,
try there, around the edges.
