Yes - the example config you gave very specifically ignores "www." at
the start of the Host: header, and sets $domain to the rest.

If you want a different part of the Host header, you must decide what
exactly you want, and write a config that does that.

I think that that says you want the capturing regex (\w+\.\w+)$ so that
you will keep the last two dot-separated parts, such that www.example.com
becomes example.com and www.example.co.uk becomes co.uk

Without testing, I'd guess that

server_name ~ (?<domain>\w+\.\w+)$;

probably comes close to what you want, assuming that your regex engine
inside your nginx supports \w.
