Yes, of course status levels are not the only source of linguistic variation; there's also geography, and other things also.

Note however that high-status language varies less by geography than low-status language.

Also, British English (at least "Southern British Standard") sounds higher status to me than American English in general, so I would find it surprising if an expression that struck my (American-English) ear as low status turned out to be a high-status British form. I would expect the reverse -- that is, something that sounds low-status to a British speaker being a high-status American expression -- to be more common.
