Hardly.
Harry was always the 'fun prince'. He was never requried to be permamently solemn.
I think in Harry's mind, he is still a working royal. He genuinely does not understand how his stauts has diminished since he found freedom.
And let's not forget that his royal connections, diminished though they are, are the only things giving him and his wife relevance. Take that away, and you have two at best mediocre individuals.
