True. Here is what I hypothesize to be the reason for this...
At least on my 32" Sony, the LCD panel substructure also doubles as the main internal framework of the TV. In other words, the LCD panel substructure also serves as the backbone of the TV. The pedestal beams actually physically attach directly
to LCD panel substructure. The front bezel also attaches to and is supported by the LCD panel substructure. I noticed all this when I popped open the back cover of my set, heh-heh. I'm sure your >40 inch panels are similarly constructed.
Therefore, it's easy to imagine how any force exerted at the pedestal beam/LCD substructure junction will directly transmit "stress" to the LCD screen, which likely is causing the clouding. I picture alot of users pushing against the bezel to slide the TV into its final location on the stand. Some users maybe grabbing the TV by the pedestal and bezel as they lift it up, causing alot of torsional stress. I personally did this when I picked up my TV by myself and placed it on the stand. I think the manual recommends carrying the TV only by the lower bottom corners of the bezel. In retrospect, I should have gotten someone to help me. With this in mind, I suggest having someone help you carry, lay down, and stand the set upright during the destressing procedure, if you are not already doing so. Otherwise, you may be undoing the destressing. Alot of stress may also be occuring during shipment.
Of course, if my hypothesis is proven, then you could easily argue that Sony should have made the LCD substructure stronger.
Anyways, just some of my thoughts. Let us know how the destressing goes.
