Would it bother you to walk into a store and see a mural of the Holy Family as being African or Japanese? Why? If you think it is the lack of historical accuracy then do you get upset at the mention of three wise men or of Mary riding a donkey? If that is the reason why do you not get upset at portrayals of Mary and Joseph as if they were Nordic types?
(Genesis 1:27 KJV) So God created man in his own image, in the image of God created he him; male and female created he them.Notice that both sexes are mentioned but no racial types. God is the creator of all and the Father of all who are redeemed, regardless of physical characteristics.
