You're always making a statement about the resource identified by the URI,
not any particular representation thereof.  So the answer is the former.

If the resource chooses to identify individual representations separately
via the Content-Location header, then make the statement about that URI.

From RFC 2616, section 14.14

   The Content-Location entity-header field MAY be used to supply the
   resource location for the entity enclosed in the message when that
   entity is accessible from a location separate from the requested
   resource's URI. A server SHOULD provide a Content-Location for the
   variant corresponding to the response entity; especially in the case
   where a resource has multiple entities associated with it, and those
   entities actually have separate locations by which they might be
   individually accessed, the server SHOULD provide a Content-Location
   for the particular variant which is returned.
