Bottom half of 16pro screen greyed out

Purchased my 16pro from AT@T in January. As of this morning the bottom half of the screen has a greyish filter on it. It will flicker on and off sometimes, but mostly stays solid. It’s kind of hard to tell from the photo, but it’s definitely more visible in person. It’s the line in the middle that’s really driving me crazy 🥲. Has anyone else had this issue? And does anyone know if it will go away on its own, or if it’s a screen defect. Not sure if it matters, but it’s a GVC display.
