Do not know about that.I am sure of the picture affixed on their Visa page...
But not sure if they had applied via Express Entry or PNP ?
Could it be possible if they have been Nominated thru any PNP ?
But i have seen at least 5 people who have posted the picture of their Visa page after getting it stamped, on the net. None of them had their respective photos. But, as you mentioned one photograph was affixed with the COPR.
Yes, all of them were Express Entry profiles.
I do not think, there is a reason to worry.
Double check your name spellings, expiry date, etc. You are good to go.
