The aliens in the Expanse universe are also very alien and difficult to understand. Which makes their technology and civilization (for the Ring Builders) quite interesting. But yes, the point of the book and even the 2002 movie was that Solaris wasn't human, and yet we keep trying to understand it as it if were a mirror. That seeking out alien life is really just seeking out more versions of humanity. Which was Lem's way of criticizing popular science fiction. Most aliens are either presented as humanoid or monsters from our nightmares. But Solaris is something else entirely. I would say the Arrival aliens are pretty alien as well, even though they do manage to communicate their language to the main character.
