The bloom effect will cause a problem here because it will be 'bleeding' HDR bloom into the dark area. What if you do actually want something very bright surrounding perfectly by darkness?

The article mention LDR on conventional DVDs.
Is the data on current DVDs consider LDR just because of the resolution or just because of the color data that is encoded? If it has nothing to do with resolution and just the color data encoded on the disc, do the HD-DVD/Blu-ray formats (MPEG-4, H.264, or VC-1 codecs) allow for the encoding of HDR data?
It seems a waste for companies to already be preparing these next-generation optical formats that won't take full advantage of these new displays.

As for the encoding of HD-DVD/blu-ray.. great question. I'd like to hear that one myself. If the encoding doesnt support a HDR color range that could be interesting. Of course, somethign like that could always be updated in the future using a firmware update. But to do that, there would need to be some sort of connection on the DVD player to uplink it to a network and what not. Possible, but unsure how the next gen dvdplayers will be equipped.

The display looks even better compared to the normal LCD's in light.
Todays gfx cards do everything in floating point 16 bit or more, this gives us the ability to do stuff in HDR.
3dlabs, ati and other manufacturers have products available to send more than 8 bits to a display using dual link dvi. Single link is only 8 bits.
HD-DVD's are just higher resolution and bitrate encoded movies. There is no codec available to play higher bitdepth movies, for now anyways :P
