The server providing the FHE-based service does not gain any sort of insight. This is a key point: only the client can see the output of the computation.

Interesting. I have some homework to do then. Do we have to close our eyes and look away for it to be true or does it really not gain any insight?
Where can I find out more about how this could be possible?

this is only true in the IND-CPA model for most "practical" FHE work. So a more precise way to describe things is "a server who faithfully performs the task given to them does not gain any sort of insight" (perhaps with an additional caveat about decryption failures).
