I thought I might elicit a response from you, well I hope?

And if you had bought the LCD you originally planned to it would have been sold to buy the Panasonic and then still the Pioneer...

On ye olde CRT sets such things were fixed in 20 seconds with a tweaking stick, now it's a design issue  requiring a whole new TV!

The whole point of using YUV in the broadcast chain is so that small discrepancies in level (during conversions or analogue paths) are not very noticeable as they don't cause a colour cast like an RGB path does.
