Wrinkly “collar” post op?

Hey guys - uncircumcised guy considering it, but had a question. Looking at sites like bidair’s there are guys like #7700 and 2560 that have this wrinkly collar behind the glans. Whereas there are sometimes guys like #1125 who don’t. Is this collar just an immediate post op thing? Does it go away and smooth out like a RIC? Or is 1125 just more aroused in his pic? Not sure what to make of these differences (and would NOT want a wrinkly collar if I got circumcised). Thanks!
