Additional Line observed in UITableviewCell even when we have set the line separator to none in iPhone 12 series devices

I am getting a grey line in UITableViewCell. I debugged with all possible ways, but I couldn’t figure out the root cause. In addition, this issue occurs only in iPhone 12 devices running with iOS 15. Please share your inputs.

Here, I have annotated the line separator with a red color box.

Adding to the aforementioned points the above-reported issue got replicated in the same iPhone 12 device running with IOS 14 as well. Hence it is a device-specific issue.
