Polished as in having a more "modern"/user friendly UI? I'd say the UI is the least important part of a password manager. Especially if you use an extension for autofilling/autosaving, you barely ever see it.
No, polished as in a functional browser integration and mobile app. For example, 1Password can fill in specific apps on iOS whereas I haven't found a KeePass app that can.
Anyways, there is a more stylish web UI for Keepass: https://keeweb.info/
