Just recently I have noticed the quality of the display has deteriorated. This seems to be mainly associated with displaying dark colours (but not pure black). It is most noticeable on the home screen, icons and wall paper and when watching videos on Kodi. On the home screen it makes the wallpaper look very light and loses sharpness as do the icons.
Changing settings in Display, Miracast(?) has some effect but I can't get it perfect.
Has anyone else seen this? ie has a software update introduced this 'feature' or is my screen potentially on the way out?
