Samsung messages: some profiles have a bold circle

Trying to find out what the significance is about the contact pictures having a bold circle BTW I am using samsung messages

Hi so I went back to verify if that were the case but it doesn't seem to be the case in all instances because i know one of the contacts doesn't have rcs and then one of the contacts does but is not boldened

It's ok I thought we were on to something
