Yesterday I went to the store again to take a better look at the screen. I had two friends with me, they were standing by my sides and while I was using the phone I asked them both several times how the viewing angles were. Both always said "good, I see everything perfectly".
Viewing angles were indeed iphone-like, much better than on another Xperia Z I tested two days ago, this is strange (though not surprising considering how 50% of users and reviews say the screen is mediocre and another 50% say the screen is great).
