  The reflected/refracted rays get "supersampled" by all practical means when
new rays are shot from the camera which are very close to the previous ones.
That's the logical and most practical way of doing it (one reason being that
the change in color may be caused by the reflecting surface itself, not the
thing that it reflects).
