Redden canvas compare to auth

Hi, the PM has been reviewed a ton so I am going to skip that part. My concern is I have yet to find a Monogram canvas that is even close to auth! Every monogram bag I have, from a variety of sellers, always has a duller canvas. Anyone know how to brighten a dull canvas? It is quite a obvious difference in person. Three pics here of a rep PM compared to a auth favorite:
