I'm coming from a Galaxy S8 Plus which looks dimmer and yellowish in comparison to my GN10+. I have both with settings full brightness and red and green bars off and blue bar max. The screen of the GN10+ looks white in comparison and I am well pleased but I can understand when coming from even brighter model phones this can be a dissappointment. I am very happy with the US version screen.
Ended up selling mine the display on my mate 10 pro had a night and day difference in white and color temp but it's running a custom ROM so that may force the full brightness more than a retail ROM the note 10+ had a disgusting display calibration I doubt it's the display but The forced calibration itself was just terrible which Is a shame as it destroyed the phone for me I did like the rest of it
