I don't think we'd be more clear by saying this, I think we'd be (at least partially) wrong.

Let's compare two worlds: World1 contains a population of pigs that are all constantly superhappy. World2 contains a population of pigs that are all constantly supermiserable. Clearly, World1 is objectively better than World2. If some morals deny this, they are wrong.

Things can only be good/bad for conscious beings (not for rocks, e.g.). So insofar the world takes the form of consciousness that gets what's good for it, it's objectively the case that something good has occurred in/for the world.
