I am very familiar with the various virus symptoms in the Liliaceae family (Lilium, Tulipa, etc.) and the Iridaceae family from the bulbous genera. (I've not studied the rhizomatous genera that include bearded iris.) I would be very surprised if there is a difference between viral symptoms in bulbous versus rhizomatous genera in Iridaceae. To my knowledge, there are no viral symptoms shown on this thread at all.
