Franco, those AMOLED settings are pretty good but one thing, when you switch to the tiles its hard to distinguish between the different shades of grey each tile has.
Try these and it will still be AMOLED settings but the greys are better:
But the colours are very vibrant so dropping the Mids down to 39 will make it more realistic but still punchy with deep blacks and bright whites. Really good settings for the IPS display and comparable to iPhone 5 display.
If you have had a Samsung phone and prefer the 'dynamic' screen mode (rich/vibrant) then keep the mids higher at around 70-80. Otherwise 20-40s looks perfect with the IPS display and similar to Samsung 'standard' mode (realistic).
