JPEG is an acronym for “Joint Photographics Experts Group”. So I guess “JPEG” refers to a collection of humans. They specified an image format also called JPEG, which has been implemented as the JPEG file format, whose filename suffix is “.jpg”

What I'm saying is that at no point was I confused about what they were trying to communicate, so as far as I'm concerned it makes no difference outside of just being pedantic.
