Dash display in 2015, seems like some models have older dash

I was wondering if anyone was in a market for a Prius V and was holding off to get a 2015 model due to the better crash ratings, but I actually liked the dash in the 2014 models more then what i saw advertised on Toyotas side for 2015 and newer, however as I look at used Prius V on cars.com, I am seeing a tone of 2015 with the older dashboard where the mpg and odometer/trip are the 7 segment displays with the clock just above, and I actually like this display more, but I cannot figure out why I am seeing these in 2015 models. What trim is it on, I would like to get the new Walnut 2015 with the older dash board, it seems like at this point is it possible to come across but I am not sure why there is a mix of different dashboards for this model year, and how I can now I am looking at the right trim to get it. Thanks for any help why this is.
