          def self.formatted_display_name(user)
            return "@#{user.username}" if !SiteSetting.enable_names || user.name.blank?
          
            full_name = user.name
            full_name_normalized = User.normalize_username(full_name.strip)
            similar =
              full_name_normalized.gsub(" ", "_") == user.username_lower ||
                full_name_normalized.gsub(" ", "") == user.username_lower
            if similar && SiteSetting.prioritize_username_in_ux?
              "@#{user.username}"
            elsif similar
              full_name
            elsif SiteSetting.prioritize_username_in_ux?
              "@#{user.username} (#{full_name})"
            else
              "#{full_name} (@#{user.username})"
            end
          end

TLDR; the @username is suppressed if it’s “similar” (e.g. Name Surname with a Name_Surname username).
