:::::I see no attempt here at passing off, and to pretend that there is, is actually way off the mark, and the attempt to argue the point by dstinguishing  'pictographic' from the 'heraldic textual description' is perhaps further off the mark. "Official flag", "Official Arms"? It is not sense, and we should not keep seeing this repeated. There may well be a lot of emotion associated with a Flag: formal ceremonies raising and lowering at the beginning and ending of the day at a military establishment, or daily saluting a flag or in many other circumstances intended to inculcate identity, loyalty or hegemony. But, Coat of Arms? G.K.Chesteron to F.E.Smith Chuck  it, Smith!; Samuel Butler on "Discobolus": O -! O Montreal!
