Untagged images are a free-for-all - any app or framework can assume whatever it wants for a color space with them, so there’s no “wrongly” about what Mavericks does. It’s just different to previous versions.
So far as I am aware, Apple is (strongly) discouraging the use of Device RGB, for the good reason that using it leads to inconsistent results.
