That is only true if you live in a civilized country. However even in GB
there is a law that requires you to hand over the key, otherwise you are
considered as a criminal.

That is not necessarily the case. Assume you live in a lawful country.
They should prove that a random-looking partition contains sensible
information. There is presumption of innocence. And you always may
declare that you clean the disk from private photo, for example. However
if a partition contains an indication that it is encrypted, such as luks
header, and even prompts to enter a password, they can justly demand
this password (if there is an appropriate law).

So I still think that a bit of overhead to hide encryption may
considerably increase security.
