iPad Air 2 screen/LCD defect on left edge of the display.

I am having iPad Air 2 64GB model running iOS 9.0.2. First let me clear that it is not a software bug and i have tried software troubleshooting.

If carefully observed,the left edge of the display is not properly illuminated.It looks like as if a black shadow is running alongside the left edge.Many users have reported this issue on Apple discussion forum also called-Book Spine Effect

IPad Air Screen Book Spine Issue

But i don't see any progress over such threads.Maybe people have learned to live with that thing or have stopped buying iPads.

I,first visited Apple Authorized Service Provider who told me to call Apple Care India who in turn asked me to provide feedback about the defect on the Apple Feedback site.

The Service Provider has also confirmed the issue present, not only in my device but in all iPad air 2 models.I have personally visited 5 showrooms where this issue was present in all the devices.Its a manufacturing defect.

I am attaching images,not sure whether you will be able to spot it out because on camera photos its not that visible.You have to physically hold the device and notice the effect.If you don't own iPad Air 2 and want to observe this defect,visit any store who are having iPad Air 2, open anything with white background at low brightness.Notice the difference between how the text on left edge looks and how does the same text look when you hold the device upside down so that right hand side text comes on left edge of the display.The issue is more observable at lower brightness because low illumination/light will not be able to reach the edges.
