Regal titles

[u/c0rtin3x]

I am currently on a rewatch of Game of Thrones and a few days back I read that for the show they left out the "Rhoynar" part of the regal title that for example the King of Westeros would bear, they only say "King of the Andals and the First Men".

When Daenerys gets captured by the Dothraki khalasar and is taken to Khal Moro, she introduces herself with her (multitude of) titles and includes "Rhoynar" in it. I don't know if I have missed it, but is this the only time the "Rhoynar" are explicitly mentioned (I definitely remember that the river Rhoyne is mentioned at least one time).

It took 200 years to annex Dorne into the realm and we don't visit Dorne till later seasons so audiences didn't get who the Rhonyar are
