Not being a historian I can't be specific about details, but I understand the uniforms and other regalia and trimmings worn at this and some other civil ceremonies were created in Victorian times. I wasn't referring to the actual events of course which are mostly historically verifiable, just the presentation. For more than that you'll have to ask historians, I don't have their knowledge, and frankly I don't find this subject important, agreeing with you on the greater importance of the content of your last sentence.
