here is a pic.

I could not get closer than C alismatifolia. I'm in Australia of course. There seem to be so many so called "named" siam tulip type curcumas on the market and very little difference between some of them.

It may be tough to get a specific id for your plant. There is a multitude of hybrids, not all of them named. The grower may not even know the true parentage of the plant(s) they are propagating for sale. I'll have to leave the SC culture to someone more familiar with growing them in your area. Yours is a pretty one--I'm not that big a fan of the more commonly sold pink here.
