It could be, although I think it shows too much white on the standards to match either one of them. The problem is there are a LOT of named irises with that color pattern, up around a 1000 in fact. There are probably at least a couple dozen that match it so closely it might not be possible to tell them apart even if they were growing next to each other.
Purple/violet plicata markings on a white ground is a pattern that been around since the very beginning of bearded iris breeding and they continue to be introduced to this day. They might be the most difficult type to get an ID on because there are just so many of them.
