Only that if the station exists in game, but the picture in the Codex doesn't resemble it when it's eventually found, that would be a bit strange later.
The Colonia, Thargoid and Guardian pictures are clearly in-game renders (I could duplicate the Colonia one very closely with a little patience to get the lighting right) ... while the three superpower and Individuals ones are clearly not in-game (Raxxla and Corporations look to be heavily post-processed in-game renders). The Codex one looks like an in-game screenshot with no more post-processing than the Guardians one, so it would be odd if the station was eventually found orbiting an A-class star instead.
FDev don't always apply that level of fidelity to placing of assets - the Zurara should have been in a system with an ELW (based on the novel admittedly, not a screenshot).
In addition, even if the station is in a red star system, the image looks a little too contrived. It wouldn't have looked anywhere near as pretty if the star was a little dot 1,000 Ls away. We'd have to assume FDev planned (in 2014) for it to look pretty in a screenshot, or just happened to get really lucky. Neither of which seems likely.
Finally, to my knowledge nobody ever found the body used in the Horizons menu screen - or even anything remotely like it.
It looks like an optimistic assumption to me (but I'm very cynical
).
Thanks for the info on the other Codex images though.
