Sam's Club output profile
Send the same photo file to the same Sams Club on four different occasions and I bet that you will get four different variations of that same print.
Do the same for a top quality lab such as White House Custom Color, etc. and you will still get 4 different variations of the same print, the vaiation will be small but there.
If Sams Club has an auto-correction feature in their processing then the photos are going to be all over the place.
It's just best to print your own.
