If you are happy with it and it doesn’t buzz, I wouldn’t bother. As long as you are happy with it and there’s no buzzing, it’s fine. What you like and what someone else likes after that is personal preference. If the saddles sit low, then fine. A lot of my guitars are like that. You may find that the bass gets set up to ‘factory spec’ with more bow and a higher action. Factory specs are far from the lowest easiest setup you can achieve, they just ensure that after shipping, the bass (or guitar) should play without buzzing if put straight on the wall. And it’s not time consuming to achieve. But often it’s not great at all. It is a starting point. From the sound of it you’ve got it better than that already.
