What is this actuality? How do we measure it in order to compare our models of reality to it and label them "less than actuality" or "closer to actuality"? We don't; we can't. We can only compare to each other's models, but that's a different thing. Can any of us say, "Hey, your model of the universe is wrong and the collective consensus is right"? That's how flat earths get made.Yes, but one will be a more accurate reflection of actuality (truth) than the other.
Each of us operates within the paradigm or model that we construct to understand reality. I can say, "Yours doesn't match mine," but then that's true of lots of things about us, and it's very often a good thing. (You wouldn't want to have my nose.) There is no "right" or "wrong" paradigm, they each do exactly what they're supposed to: represent reality to one person as that person knows it. And they can change with new information, new concepts, new perspectives and new understanding.
