It's more the fact that even with the Pro we STILL can't get 60fps...really?!? Come on ffs, this joke is getting old now. We're forced to play at 30fps yet again.
As for 'colour', it's hardly a graphical achievement since you can alter saturation on any telly...but yeah ok I get your point about the world being less sinister and more vibrant.
The CPU in the PS4 is just not enough for 60fps in open worlds, I dont see many devs making a 60fps mode for a game for the pro, They are going to just throw the extra gfx power at better effects and resolution
