I was asking questions about something similar about a week ago, here's the answer I got, and I have no reason to doubt it.
There are no black and white occell.'s. The closest you get is the onyx perc, and as your pics show, they still retain orange face and fins.
Based on that info, I would say that all pictured appear to be b&w occellaris. Unfortunately, lots of places have them labeled incorrectly from ignorance or laziness (IMO) and it can make it very confusing. Just my 2c. (off the soapbox now)
Regardless of species - that's a really neat picture! Thanks for sharing it with us!
