Wipeout is more washed out on the LCD in those comparisons than the OLED. It's apparent even off-camera. Why? Because it was built for the OLED's color-levels than not-at-the-time LCD.
Same shit is gonna happen when FFX HD releases, it'll be built for LCD to where it's vibrant as hell there but looks bad or darker or what-have-you-whatever-you-want-to-call-it on the OLED.
Of course, I'd love to be wrong and have "parity" between both in regards to color-modes, but that probably won't happen. We'll probably get a setting in the firmware like the PSP to where you have to set the LCD's "vibrant" mode on for games to take advantage of it.
