Character mistake: When everyone is preparing to go in to dinner, Robert is wearing an adjustable bow tie. It's bad enough he's wearing black tie to dinner when he has guests, as his mother points out, but Robert, the Earl of Grantham, absolutely would not be seen wearing an adjustable tie with a stand up shirt collar, even among only his immediate family.

Answer: Yes, because at the time it was not sure if it would continue and since it was short it could be seen as a miniseries. it also depends on where the producers decide to submit it. However since it continues on it is no longer a miniseries but a full series and thus cannot be submitted in the miniseries category anymore.
