The easiest solution for that is that many of the binary (or higher multiple) stars that take a telescope to resolve on Earth are not visibly multiple, and spectroscopic binaries are entirely absent. At which point anyone with real knowledge of astronomy can be quite sure this isn't Earth, and never will be.

As for stars only known to professional astronomers and not visible with the naked eye, the ones Germania Hyperborea has are completely different from Earth.

Again, this isn't Earth. Somebody will have made a note that at some point in the future, a proper sky survey ought to be made, and a statistical study of the distribution of non-naked-eye stars will likely reveal non-random patterns.

What would be some expected effects on flora and fauna, as well as humans surviving there if it remained static, but varied in power, with mists covering it at various times?

An obvious effect is that shadowed areas will always be in shadow. If flora had evolved with this situation, there would be specialisations for it: plants would not need to turn towards the sun as it moves, trees would be different shapes, roots would specialise in sunlit or shaded areas, and so on. However, I strongly suspect that these specialisations are absent, revealing that the world was recently created and populated with Earth-derived life. Another scientific note for the future: Observe changes in the natural shape of fast-breeding bushes over decades.
