Difference between design fleur-de-lis design 1202 and # 1202DD?

These are two very similar looking tiles with only few subtle differences. One of the differences is the dash and dot design that is not present in #1202 and what the DD stands for in #1202DD.  The rest of the differences are not easy to explain and picture below will help with that.

Both of these tile designs come in 3 types of metals, Aluminum, Steel and Copper and there are 80 different finishes that can be chosen for the Aluminum version.
