Irises: mislabeled iris, 1 by SunnyBorders

I purchased a number of repeat bloomer irises (growing in pots) in April of last year at Mori Gardens, Niagara Falls. About six weeks later, it was clear that one plant, purchased as 'Again and Again', was mislabeled.
Have spent some time trying to identify this Iris. The closest I have found is 'Feedback'.
The flower pattern, of the plant I have, is self: color violet-blue or blue-violet: color seems slightly iridescent: beard white but yellow at the back: lightly ruffled: quite noticeably fragrant. It seems shortish for a tall bearded iris, but it had been tightly growing in a pot.
All the Irises I saw at Mori's were labeled repeat bloomers and all were Heritage Perennials. I checked with Heritage and they have never knowingly grown 'Feedback'.
An image of my plant is included (I hope).
Does anyone know what else this iris could be? Can anybody support my identification?
Thanks,
Sunny
