No, his whiskers are long and straight as pokers.
He may secretly carry a Rex gene but you need two to get the short velvety fur.
His colour looks dilute/blue and the white blaze on his face looks Dutch but could be Vienna.
A Vienna mark mini rex mix, that is if it has the velvety rex fur. Even though his whiskers aren't curly. All my mini rex were pedigreed purebreds and some had pretty straight whiskers.
