See, the funny thing about things like "Thrawn" or "Tie Defenders" being canon, is that they AREN'T the same Thrawn or Tie Defenders that we knew before. The Thrawn of Rebels isn't the Thrawn of the 90's novels. How do I know that? Because the 90's novels didn'T happen.
It's the armor, I suspect he is a paladin though.
