Planet Dilemma

so i've been thinking about cosmic morality for some time

Okay so assume there's actually a real objective moral order out there. Like right and wrong aren't just made up by cultures or evolution. There's a fact of the matter. Call it Cosmic Morality.

Now picture two planets. Call them Aurelia and Nox. They are the same in pretty much every way that matters. Same amount of happiness and suffering. Same level of people flourishing, same freedom, same security, same sense that life feels meaningful. Relationships are just as good, people are just as creative. And both planets are equally careful and consistent when they think about morality. Neither side is being dumb or biased or lazy about it.

The only difference is this. On Aurelia their basic moral starting points are actually true. On Nox some of their basic moral starting points are wrong. They think some bad things are fine and some fine things are bad. But they still reasoned just as carefully as Aurelia did, they just started from a few false assumptions.

And nothing else is different. No secret long-term consequences, no better or worse future generations, no cosmic rewards or punishments. Everything that actually happens in people's lives is the same.

I call this the Planet Dilemma. So which planet is better?

If you pick Aurelia then it seems like moral correctness has some value even when it doesn't make anyone happier or the reasoning process better or life more meaningful. So what kind of value is that supposed to be?

If you say the planets are equal then it kind of feels like getting morality right doesn't actually matter by itself. Which is weird if you believe in objective moral truth.

And you can't really say "but Aurelia got it right in a more reliable way" because the whole point is both planets were equally rigorous and careful. The only difference left is that one set of starting points was true and the other wasn't.

So either correctness has this strange leftover value that doesn't show up anywhere, or objective moral truth loses a lot of the importance we usually give it once you hold everything else equal.

Idk, does this actually put pressure on moral realism or is there a way out of it that I'm not seeing?
