Control by voice seems a bit daft, and I really don't believe the colour space claimed, but the"white" colour needed can depend on several local details. Did the decorator use "white" paint or "magnolia"? A slight change might make the TV look better. I know some people don't even bother setting up their computer screen properly.
I can recommend http://www.lagom.nl/lcd-test/ as a check.
Just getting screen brightness and contrast as near to right as you can makes a huge different, and ambient light is a factor in that. I still have a cache of photographic filters marked up in Mireds.
