Are you viewing the set in a dark (no lights) room, or in a room with some light? The darker the room, the less likely it is you need max on Picture/Contrast.
Blooming doesn't apply to anything but CRTs, it's impossible with fixed pixel displays that use lamps or backlighting. Plasmas won't bloom either.
There is a danger you can lose detail in bright scenes with pic/contrast up too high. Each brand/model should be checked with a gray scale step pattern that has above white (and below black) to make sure steps are not 'lost' when pic/contrast is set high.
The 60" XBR2 sets are VERY bright, powersave mode is pretty much mandatory as is using a small iris setting or Auto2 mode for the iris. These settings reduce max light output and bringing the pic/contrast control down below 90 also knocks the edge off the high light levels. Even at that, if there's a completely white screen displayed... holy crap, it is REALLY BRIGHT in a dark room - like squint-to-prevent-discomfort bright.
The 70" set spreads the same amount of light over a larger area so the peak brightness levels are not as high as with the 60" XBR2s. But the 70" sets are STILL pretty darn bright. If you're not bothered by really high brightness levels when a completely white screen is displayed, there's probably no reason you have to turn down pic/contrast since these Sony sets don't wipe out any of the steps in the gray scale when you use high settings for pic/contrast.
All that said... over its useful life, the lamp will lose as much as 50% of its brightness so compensating over time by jacking up pic/contrast and perhaps turning off powersave mode or changing to a larger iris opening would compensate for the loss of lamp output. So depending on where you are within the lifespan of your lamp, you could have pretty different settings controlling screen brightness.
