Does Refinements Give You a Better Result?

im wondering do refinements correct your teeth to reach the same result your initial clincheck shows you if your teeth dont turn out the same result in the first round treatment or those refinements can correct your teeth in another level and give you a better result than the result they show you in the first clincheck? I ll be super happy if they can make my teeth tighter and look better during the refinements than the result they just showed me in the first clincheck.
