Do my zirconium crowns looks yellow? Chose b1 shade ( photos)

hi, i'm 28 , i'm white but not super white (north african) , so i had my zirconium crowns done (all my teeth) , i chooses bleaching in first then i saw this video on youtube someone had bleaching veneers and omg they look fake miles away, and i changed my mind to the whitest natural shade b1 .Now i'm confused in some lighting they look yellowish color even in the natural lights looks not as white as the artificial lights, i contacted my dentist he said that was my choice. what do you think?
