I agree it is Rlc. Digbyano-Purpurata for two reasons.
It looks exactly like the remake of this early 1898 hybrid. That was when hybrids were so rare as to be able to name them by the parents, hence the name. Obviously we can not so that any more.
The second reason is that this plant was a recent remake by Better Grow products, who sell to Lowe's and Home Depot. About a year ago they released thousands of blooming size plants that are now flowering.
Your flower looks like a first time flowering. The flower will improve the next time it flowers. I have a picture in my photo gallery at
