I think there's a distinction between acceptable and right. While I concur that some games have had acceptable amounts of bloom, I would argue that vanishingly few, if any, have actually gotten it right, mostly because getting bloom "right" is extremely difficult and requires deep HDR analysis.
It depends on your basis for comparison. I'm comparing them to old games that did not have any bloom at all, not high quality renders.
Bigger problem, last I heard, was still the lifespan of the OLEDs themselves. They're not quite up to snuff yet I think. But they've made a lot of breakthroughs in this area in the last year or so.
The problem with the blue lifespan was apparently solved quite some time ago, at least on lab prototypes. Unfortunately, it seems like we're not going to see any mass-produced models until 2012.
OLEDs will have numerous other advantages over LCDs, even if we don't see them support any HDR color modes.
