Seeing may be believing, but measuring is truth.
Do you believe that the color improvement was caused by the florescent (or LED) bulbs in your TV sending out "better white" light, or by the three LCD layers in each pixel just getting opaque more?
Or does something special happen to LCD material when "better" power is being fed into the AC/DC converter?
When you can blind A/B: let me know.
I know people who swear by high octane gas in their low-compression cars without understanding what octane is or what it does or why high-performance engines often use it.
