I have the same question. In my case they stamped the photo without the details to the COPR, which is the same photo the immigration officer took during my Landing.Thanks!
But since out of the 2 photos submitted during copr, one is on the copr and the other returned, based on which photo do they process the PR card? Is it based on the one in copr that we hand over to them during landing (the IRCC copy)?
How will they know if it was taken less than 6 months ago?
