Re: Something about S6
Go to DisplayMate and find the article "Galaxy Note OLED Display Technology Shoot-Out"
Read through "Multiple Screen Modes and Color Management" and "Adaptive Display Mode with a Wide Color Gamut"
DisplayMate concludes "the Absolute Color Accuracy for the Basic screen mode is an impressive 1.6 JNCD, tied with the Galaxy Note 4 for the most color accurate display that we have ever measured for a Smartphone or Tablet. It is visually indistinguishable from perfect, and very likely considerably better than your living room TV or any display that you own."
You seem to know one thing about AMOLED but none of the other 99 things.
Can Be Controlled? Yes
Best color accuracy? Still Yes
