Sony Xperia Z5 Premium screen pixelated when on landscape, and square grid dots on screen.

[esv80]

When I turn my new Sony Xperia Z5 Premium on landscape mode, I can faintly see many horizontal and vertical lines accross the screen.
But when I turn back to portrait mode, you can't really see them anymore

I tried the 4K images and video to see if it was only a down-scale issue, but it wans't. Even at 4K, I could still see them.

Lastly, I used a magnifying glass, just to make sure I wasn't seeing things, and I there they were, much more noticable under the magnifying glass.

It's rather annoying. I want to watch YouTube or Websites in landscape mode, but the screen will look pixelated. Reminds me of the old QVGA screens. Loses the clarity and crisp of the images, videos, etc.

Also, there seems to be dots, LEDs, I'm not really sure what they are, in my phone's screen, regardless whether my phone is turned on or off. They can be seen when light gets reflected from the screen. I did not have this problem my Z1 or Z Ultra.

If its a screen defect, please let me know, so I can return the phone while it's still brand new conditions.

Thank you

If so, what's wrong with it? It looks a million x less pixellated than the one on left.
