At normal settings, even in the dark, it is not visible. I don't consider this a defect in my case. In the case of someone who had more severe backlighting issues, it might be different. My point is, a lot of people have unrealistic expectations about what this technology is capable of. Lumping all backlight uniformity issues together is ridiculous, since it is present everywhere and the more minor issues are expected and are NOT defects.
I really wish people would stop with this BS, because unless they've seen it firsthand, they just don't know what they're talking about. The cloudy/splotchy backlighting that is seen with these panels (I've returned THREE Samsung 5296Ds due to this issue) is NOT acceptable, and is not something that is just "normal for all LCDs". I've used at least 6 different LCD panels on computers, going back a good 10 years now, and though they've all had uneven backlighting to one degree or another, they have never had the odd cloud-like splotches that these Samsung/Sony panels are displaying.
In addition, my replacement Sharp 52d62u that I just got yesterday exhibits none of this splotchy backlight problem that all three Samsung panels had (ranging in build date from late September to mid October). Unfortunately my Sharp does have the banding issue that that set is now infamous for, but at least Sharp has acknowledged the problem, and is dedicated to fixing it. In my numerous calls to Samsung, I got NOWHERE with this issue. In fact, when sent the photo below, they said that this amount of "bleeding" (which this certainly is not anyway) was within acceptable limits.
As an aside, the Sharp also has NOTICEABLY better shadow detail than the Samsung panel ever did (both calibrated using Avia in the lighting conditions of the photo above).
