Me too. Quite disappointing update.
My Samsung S8+ in adaptive mode looks ok from direct viewing angle.
The problem is the the Infinity Red Display screen will have red tint when view different other from direct viewing angle, which this software fix can't do much. If drag all the way the screen become too blue, and there's still great change of color when view from different angle, so every time I tilt the screen will immediate notice red tint, which is quite annoying.
I tested some display set at store, some of the set (yes, S8+) don't have this problem, so it is definitely QC problem which doesn't pick up defect red screens and let it pass.
