Eurogamer is really 360-biased. They're practically the definition of a fanboy magazine. They are way on the bottom of the bell-curve, as far as average PS3 game rankings go (they may even be THE bottom, as far as major publications go) -- that's a pretty clear indication of bias.
That being said, it doesn't look like they're bright enough to set their PS3 to full-range RGB... I don't expect much more from fanboys who don't know how to operate their PS3. They probably hate Sony Bravia TVs too.
I have all three consoles, and several of the games they've mentioned on both HD platforms (for reasons I'm not going to discuss) -- they have different requirements for the output to look good on the TV look at them on -- if you make one console look good, the other looks bright/dark/muted/color bleeds/etc.
