Ok. Definitely different to the cl.700 equivalent though, as you can see in macaron's post above. I think the depictions used on the 700s look neater myself.
Another thing I noticed when I rode the 707 (on 17th Aug), was that despite being a 10car, the PIS will only show carriage loading for the 5 that you're on. So, I assume then that if you're in say coach 7 of the 10, it'll incorrectly state you're in coach 2? Or have they accounted for that? I didn't check personally as I was right up the front.
The one I was on today was correct telling me I was in coach 6.
As seen in this photo from the first day in service:
