Jim,
The three irises you named are older hybrids. Your photos look like
a more recent hybrid. A more recent hybrid for example: Swans In
Flight (2006) flowers have a more similar form to your photo. I'm
not saying your photo is Swans In Flight, but the iris in your photo
is probably a more recent Iris.
Just my opinion from looking up lots of irises over the years.

White Swirl shows up in two different ancestors of Swans In Flight,
a parent of Pink Haze and grand parent and great grandparent of
Springs Brook.
Snow is finally completely gone on my garden today, but it's too wet
to walk on.
