Yes. To find out whether a document is formatted in some language it is necessary to fully parse the document. That’s true of every language.

> Canonical and non-canonical N-Triples advertise the same Media Type in HTTP Content-Type headers and have the same extension in file names.  It's nice when data publishers use the canonical N-Triples format, but since the data consumer cannot anticipate that this is actually the case, this does not make the situation easier for her in practice.

My experience is exactly the opposite: When publishers and tools produce Canonical N-Triples, it makes my situation as a data consumer very much easier in practice, while in theory it doesn’t make a difference.
