Does the PS4 Pro make regular games look better than regular PS4?

As an exclusive xbox user who is looking to get into the world of play station, how exactly does the PS4 Pro make the games look better? Like I don't see any 4K specific games. For example, if I was to go and buy Battlefield 1 and play it on a PS4 Pro would it actually look better than it did on a regular PS4? I have a 4K tv also.
