Can a round diamond with a 65% total depth look good?

Most rounds are cut with a total depth of 60-63. Can a deeper cut actually look good, or is it just a waste of carat size and dead looking. If you have actually seen the difference, please chime in!!
Thanks

They wont match a better cut stone.
But they can look decent but why pay for weight you cant see?
