I have a 4K TV and I can notice a difference, but only from single player games. The main concern with a "Pro" version of anything is trying to get the developers to make improvements. Sadly there's always the benefit =/= cost and currently most developers don't want to spend resources towards something that will affect a minority of gamers. Most gamers don't have a pro, and thus this creates pressure on Sony to reach out to developers in order to push for that support. The pro is simply a luxury and I bought it with that in mind. Also, its main purpose for me was to use VR. That is where the pro shines imo, absolutely crushing the benchmarks of the regular PS4 in terms of VR performance.
