You know, that's a good point, on a television it will already look brighter, so it may be best to just leave it alone.

And as for the colors, they seem quite strong already in the unchanged V3, and now that I look more closely, Luke's face does seem a bit yellowish in the tweaked screen shot, so leaving the color saturation as is might be good, too.

Taking this into consideration, I'd say leave the V3 as is, no brightness or color changes.

Can we get a comparison shot using these same settings showing Han and Leia close up talking on the Millennium Falcon? Would be good to see the flesh tones in a naturally brighter scene to make things clearer.
