The observer effect is irreversible. Quantum mechanics is reversible only because it the effect technically falls outside of the mechanics.
In related news, the entropy of a closed system is usually not constant.

Wouldn’t the act of observing be baked in from the start, and therefore accounted for?

I don’t know what you are trying to say. But you can’t predict the state something had before you observed it from the stuff you see.
