GPG's keyserver code is capable of displaying expiration date, if the keyserver provides it.  Not all do.

But - and this is important - like all key data (from expiration date, to revocation status, to the user IDs, etc), the info returned by a keyserver is only informational.  You cannot rely on it until you download the key and check it yourself.  The keyservers are simply storage, and do not verify the keys sent to them (and you shouldn't trust them even if they claimed to).
