Ahh yes, I see what you mean. I was basing my ID on the spotty blotch on the upper petal of your linked image where mine was a more solid color blotch but not entirely solid colored like the one I linked. But I also based it on the one you linked having that lower petal looking almost white compared to the two side petals where mine have the same colored petals all around.
But there can be so many variations in any strain, I see it all the time with these little violas. That's how I pick them out at the nurseries, find the one oddball among the trays of plants!
