Backlight Bleeding On The Black Screen Of My LG 75QNED816RE TV

54,000 TL for the LG 75QNED816RE model TV. It's been a week since I bought it. There is light bleeding on the top right and bottom left corners of the screen. I opened a service request and received the response, "Such a situation can occur depending on ambient brightness and light conditions." When I requested a replacement, they said, "You can get paid support from our service if you wish." What do you mean? I don't understand why I should get paid support for a TV that I bought brand new with a warranty just a week ago! In other words, they are not replacing the defective TV. And shamelessly, they say you can get paid support from the service. LG is a regret.
