If sony is using VA LCD display, it has better contrast and colors compared to IPS who only have better viewing angles.
But sony is always not disclosing some of their materials due to "licensing" or "copyright" issues.
We know of people out there being paid to advertise, promote and sell goods.
There are also those being paid to defame, troll, bash or make untrue statements for competitors.
Most people only look at flaws without noticing the goodness and thus, did not realise the good stuffs they missed.
I personally think that viewing angles are overhyped, only exists after fans attempted to brainwash the world with the pros of OLED display.
Same goes for fruity fans going on with - only android needs more cores since fruity phone is "lagless".
Oh yeah, compare side by side the gen 1 to gen 3 fruity and you will see what is "slowness" instead of lag.
Imagine sony fans stooped to low means and go around saying - my walkman is better than your lousy music player.
Now it sounds as bad as excuses like "viewing angles" or "lag".
