Seconded!

This would be even better than the solution proposed in:

Would it be possible to get some kind of low-resolution image of the current output of the TV?
I.e. a picture of 16 x 9 pixels with the correct averages would be more than enough to build a DIY ambient light.

PS: I do understand that outputting the image is not possible with the DRM in place. But a downscaled version may be possible?

Seconded. Ambilight is the only feature missing from these great TVs.
