I can’t tell if the background is a very clean real interior or a render, either way it makes no sense for it to be like that.
Everything about the scenes they used feels so intentional and designed its pretty ironic to have such obvious and weird flaw.
I don’t think it’s meant to be a permanent wall, that plant wouldn’t survive there, those books might be fake? I think it’s a lobby right, weren’t these backdrops all created from lobby spaces in the spaceship? So they quickly dressed it up, or rendered it in place. Either way good reasons for a bit of misalignment.
