UCP wikis have a completely new aesthetic to them as well as a completely different editor. There is, unfortunately, nothing you can do about this. You also cannot revert your wiki to the legacy platform. Even if you could, you would be just delaying the inevitable as all legacy wikis are going to be transitioned to UCP.
