2013 Epiphone Standard Pro identifying questions

I have a 2013 Epiphone Standard Pro along with my Gibson and have a couple questions. How can I tell the difference between a Pro Top Plus and not? I know the Pro top plus has a nicer top of course, but compared to what? Also how do you identify Pro bucker pickups? I'm not sure if these are the regular alnico pickups or not. I have had this guitar for a while and it's great, but I would like to really know exactly what I have. It has the split coil pots. Any help on these questions would be really appreciated. I tried looking up the serial number and it tells me when and where it was made, but not much else.
