dell g15 display issue (Black Shadow/Stage light defect)

Hi,

After using my laptop for 10 days of purchasing, I noticed a black shadow on the bottom edge of the display. After searching on the internet, I came to know that it's called a stage light defect. My drivers are all updated and I have run all the diagnostic tests but I couldn't fix the issue. 

Has anyone faced a similar issue and got it fixed? 

TIA
