An argyll jacket is a style of day kilt jacket and comes in two basic forms.

The Barathea argyll is really a formal(morning suit equivalent) day jacket.

Now that is the black and white simple answer, but------------ but there are huge areas of grey!

Might I suggest that before you get too embroiled in the detail, you find in my old posts a thread called, I think, "The Tweed Argyll" which I think may clarify things a tad for you.
That thread did clear things up a bit. Although, the dust up over the "flat cap" left me wondering a bit...lol
