Sorry, I was grilling out earlier.
The main contributors to the "purple haze" are BrilliantColor and Dynamic Black.
I recorded the settings of my UHD60 before switching to the UHD51A for 3D.
The UHD60 has color in spades so don't worry too much about lowering color settings. In fact, over color processing adding too much color is the reason I think the issue happens in the first place.
For me, BrilliantColor was the main cause of the purple haze. I loved it at 10 but had to bring it down to 2 to eliminate the issue completely.
Here is a link to a YouTube video of me switching BrilliantColor back and forth between 2 and 3 over and over again. It's The Matrix Reloaded with Agent Smith looking through the slot in a door with car lights behind his head.
I was able to keep Dynamic Black on with the following settings but others said they had to turn it off. If you don't bring BrilliantColor down you will have to turn Dynamic Black off regardless.
Color Temperature: D65
Color Gamut: Cinema
RGB Gain/Bias: n/a
Color Space: Auto
Dynamic Black: On
I spent WAY TO MUCH time adjusting the image of the UHD60 than I did enjoying it. The UHD51A doesn't have the purple haze. It will display a similar issue if the Color is set too high (happened when my SDR's Color setting of +19 or so was applied to a HDR signal expecting -19: projector quirk).
The settings above don't address the blown out whites with very bright images/scenes. I just didn't get to it before getting the UHD51A.
