I have seen some of my games get better smoother looking lines as well as better color. The PS4 game enhancement is cool as well now. Anti aliasing looks to be added to a lot of games or maybe it's just some simple shading effects over lines and stuff. Also color detail is higher. Blue, green, red, yellow, all a lot more better and higher. Detail is overall a lot better. But it's not in all games, just some PS4 games of course. And of course if you don't want the brighter colors and the odd smoothing scaling you can always turn off that PS4 game thing off in video settings.
