Problem is, Natural has not been properly calibrated to full sRGB. They've messed that up too as the reds are lacking as shown on a color measurement video by Erica.It wasn't washed out, it was displaying sRGB as it should be, previous Android phones not on Oreo were displaying more colours than they were supposed to due to no colour management before Oreo.

Google only added the profiles to appease people that don't want accurate colours, the natural profile is what most people should be using if they want proper colours.
Add that to the aggressive blue shift, graininess at low brightness (not just on white but on the notification pull down too with text going grainy) and the crushed blacks, it's just barely a passable screen for the price. Has anyone tested outdoor brightness?
