Amateur astronomer here as well that has also done a bit of lunar photography. (envious of your EdgeHD 14...)

I made a similar comment about the moonglow, but thinking a bit I think it's a combination of: - Higher dynamic range than the human eye (combination of stars, moonglow, and high contrast lunar surface both in shadow and in sunlight) - High resolution imaging, and the digital signal processing aspect (noise reduction, deconvolution, etc.)

They combine to make something that looks kinda like reality but is really a mix, and maybe triggers a little bit of the uncanny valley effect.
