i guess i have also observed this issue since i bought the phone, the darker areas are generally off-colour. From my personal eperience a black shade lock screen wallpaper shows a very green like tint rather than black, the colour is also very pixelated one.

Same problem with my 2a also,

Anybody have solution for this problem ?
