Need help confirming if this is a normal Z3 or my if my phone is fake, or refurbished ((help!!!))

[Freqish]

i recieved my 'brand new' z3 d6653 model i bought privately off an ebay seller...

i put in the imei number into imei.info and it says it is actually a xperia z c6603...but when i plug into pc campanion it says it is a z3 d6653....??...

i was also watching a video of the z3 on youtube and noticed the glass over the camera bulged out a little bit and the led has a milky lense cover thing... mine doesnt have any of that, no bulge from camera lens and the glass is clear and can see straight to the led (which you can see in the photos bellow), and the led is also way off centre...

also the xperia, nfc, and logo next to the camera are black which i havnt seen in any pictures online, they are all silver....?

also the phone didnt come with plastic screen protectors on front or back as iv seen people have in unboxing videos...

and when im making calls people just only JUST hear me.

also the phone came with 0% battery and when its charged it doesnt seem to last very long at all (no where near a full day or medium use)...

and the camera only lasts a maxium of a few minutes just taking pictures before it overheats and shutsdown...

it only came with a little start up guide no other paperwork in the package and no extra ear buds. ....

it is running android 5.0.2 and says there is no updates even thought i have read a lot of people are running marshmellow 6........

i am confused and not happy about.

notice black xperia, nfc, and logo next to cameranotice the LED way off centre and no reflector covering it and the silver ring around the camera is different to photos onlineno bulge from on glass over camera from the lensis this a legit looking box??here are some photos.
