Xperia Z screen

So I went to a Sony Center store in Poznan, Poland and recorded a short video of the Xperia Z's screen.

In my opinin the contrast of the screen is a little bit low. The colors look good only once the Bravia Engine 2 kicks in (in photo gallery). I hope that there will be a mod which will allow it to stay on at all times. I installed Nova Launcher on the device to show how the blacks look. Although they are obviously not Amoled blacks I thought that they were good enough. The viewing angles imo are not as bad as some reviewers suggest. The screen on the Xperia Z is extremely reflective and catches fingerprints very easily (what you can see in the video). Overall, I think that the beauty of the device makes up for the not absolutely perfect screen.

I hope that the video was helpful for the potential buyers.

Please like the video or let me know if you would like to see anything more in the comments below.

EDIT 1: I found a drop test done by komorkomaniablog. They are talking in polish but you can see the action from 2:10

EDIT 2: Ok, so today I have phoned the Sony Center store in Poznan to find out if they will allow me to the a scratch test on the displayed device. Unfortunately they informed me that it is not be possible but they gave me a number to the official Sony representative.

I just got off the phone with the man and that's the information that I have received:

"The screen on Sony Xperia Z is covered in tempered glass, which is a combination of Gorilla Glass 2 and Dragontail. We have excessively tested our devices and it will not be possible to scratch the glass with normal use. We did hovewer throw the devices around to check their resistance and after forcefully throwing them on the ground (with sand) small scratches could be visible on the back of the device.
The screen of the Xperia Z comes with a screen protector and there is no purpose in removing it. "

So I guess we will have to wait for one of the end-users who are not afraid to sacrifice their device to see a real scratch test. Now, how is it possible to be both GG2 and DragonTrail? Obviously the guy doesn't know what he is talking about...

EDIT 3:
@GadgetsBoy @aedney I just got off the phone with Sony Rep. The glass is GG2+DragonTrail and it should be completely scratch proof.

@shem2409 the back isn't ill put a video up later, front is scratch proof but to certain extent.

@GadgetsBoy The guy said that the back scratched only after they forcefully dropped it on the ground (with sand) and that both f + b are (?)

@shem2409 not according to my test lol, got a scratch on the back now.

Hmmm.. looks like the back isn't all that scratchproof after all :-(

EDIT4
I just spent 10 minutes on the phone with Sony Rep. Apparently Sony uses Gorilla Glass 2 as well as DragonTrail. Devices will come with either one installed. (you might have the front panel made of GG2 and back from DT) and consumers will not have a choice of the glass used. The back panel of the phone has an additional layer on the glass which provides some glare effect (so that could be the layer that is being scratched and not the actual glass). On the front there will be a screen protector preinstalled.

Users will not have an option to select the glass used in their phone, so we will either have GG2 or DT on the front and either GG2 or DT on the back. I think that this should also clarify the on going debate about which glass is used in Xperia Z.
