Does the Xperia XZ3's screen has rounded edges or is it an optical illusion due to the 3D glass?
I understand your point, but as of right now, which Xperia do you have? do you use any image enhancements?

professional mode
Standard mode
Super-vivid mode
I have a Xperia XZ1 (probably my last if LCDs were ditched) with Professional Mode set.
This is my opinion, perhaps future flagships will have OLED and mid/low range Xperias will have LCD, we'll have to wait and see.
