I dont have your exact TV; but mine is in the same family as yours... the UN55D8000.
Is this your first LCD/LED side-lit based TV? Regardless of manufacturer, model number, and name, you will see some signs that the TV is using this technology. Some settings will greatly exaggerate these symptoms and some will hide them to where they aren't issues to most people.
There are a few options to consider:
1. Switch to a plasma TV:
Be prepared to watch TV in the dark; or with the lights dimmed. Otherwise, you lose any picture quality gained by owning a plasma TV. Brightness is the only reason I didn't get a plasma TV. Inviting friends over to watch the game in the dark. Seriously?
3. Local Dimming TV:
Pay 70% more and get a Sony XBR46HX929 local-dimming TV. This technology will offer you the same brightness as you have in your current TV; plus it doesnt have the flashlight effect from the corners of the screen. All the LEDs are placed like a checkerboard all along the back of the TV.
There is a side effect with this type of technology though, you will see a glow where each LED is placed when watching scenes with small bright objects on a black or very dark background. I had to return my LG local dimming TV LG LX9500 due to this side effect when watching space movies like BSG. I'd see all the LED's glow in a checkerboard fashion along the back of the TV when showing outer-space/space-field videos. I first thought the TV was broken; but found out that's the side effect of owning an local dimming TV. This shouldn't be a problem when watching regular sports though. IMO, the picture quality/colors from an LG isn't as nice as Samsung.
3. Upgrade to the UE46D8000.
The flashlighting effect is less. Especially, when watching movies. The cost different between the 7000 and 8000 is minor.
PS: Can you post your settings? I have my backlight set at 12. It's just right for me on my D8000.

So after I've discovered this problem I've contacted Local Samsung representative. First they even said that this was normal (even if they saw the pictures).
Also they had the audacity to ask me to put the backlight to value 4/20.
After I've took the the device in the service even if I requested to give me a new TV (because that clearly they've sold me a TV with manufacturing problems) the opted to replace the panel.
Today I've received the "fixed" TV and off course both problems still persist, now the clouding effect has mode and from what I can see it's a little more visible. I will contact them again on monday.
(I do not have the privileges to post images/links in the forum ... so if anybody can help me with this I could PM them images far both "states")
I know that this thread is for the UN model but has anybody encountered these problems? especially the second one (the vertical imperfections/shadows)
