The video comparisons on these sites suck, i play on a SDTV and my games look better then what they show on their site, i have played around with the settings and i get a great picture.
In one of the threads on GT a poster took blown up pics of the video and from what he and a bunch of others said it looks like the PS3 video is being taken from a bigger source and downgraded so the quality is even worse, this is very clear in the pic he showed compared to the 360 version.
One of the posters also showed some pics of the PS3 with full RGB on and off, here on the pics.

EDIT: One other thing that proves that GT is run by a bunch of retards, they said you need a $5000 computer to run Crysis, after weeks of trying to fix their computer.
