What's said in "Caretaker" is "...sustainable cruise velocity of warp 9.975" which indicates she can go even faster for short periods.
Exactly. IMO, all ships can in theory go faster than their top-rated speed, but usually at the risk of burning out the engines (or even flying the ship apart). The Voyager
might be capable of hitting warp 9.99 in an emergency, but probably not for very long and at extreme risk.
