Well that's a really pretty iris! It looks exactly as you describe, but hard to know exactly what it will do in your own yard. If you look at this link, there are some user photos that may give more of an idea of the variation in color it can have:

To me, it looks a bit more brown than copper.

My mom recently said she wanted one called Carnival Time. I know it's a Schreiner introduction, but I have yet to be able to find it available for purchase in the U.S. Seems more popular in the U.K. thanks to Monty Don!

I absolutely love Breve. Photos online simply don't do the colors justice, and to me, it looks more copper than the descriptions of it suggest. I ordered it online after an iris society member brought a stalk to a meeting this spring. I think I would've passed it by otherwise as I wasn't in the market for "brown" irises.
