I am a little disappointed in the warmth of the screen. Yes, OLED means perfect black - but the screen is otherwise quite cold even when the 'eye comfort' is set to vivid & warm. In fact, laying this phone beside my 1st gen OPO (which was a textbook 'cold' LCD), they don't really look all that different.
Obviously Samsung tends to go to near garish, eye searing ends of the spectrum when you have things set to 'vivid', but my 10" Tab 2 is so juicy your eyeballs explode and dribble down your face. I wonder if this screen is simply cold by hardware design or if it would be possible through software to make things warmer yet. It isn't a deal breaker, but putting this thing next to an iPhone XS (which is also considered quite 'cold', explained insistently as 'more accurate'), the XS actually looks somewhat more juicy than this thing. I don't want accurate, I want to get radiation burns from the ridiculous over saturation.
