Black spot on iPhone 11 screen

Hi,

I recently got my iPhone 11 and noticed that the lower right of the screen have a dark spot/black shadow. It sometimes goes away after restarting the device. But it’s been happening more recently after I updated to the IOS 13... Is this something Apple will repair?

I had an iPhone 7 for 3 years and never came across this problem before.

thanks in advance!
