How to fix a persistent white spot on Lenovo laptop screen?

I’ve noticed a small, bright area that is particularly visible when I’m looking at light-colored backgrounds or spreadsheets. This white spot on lenovo laptop screen doesn't seem to be a dead pixel, but rather a pressure point or a backlight bleed issue. Is this something that can be massaged out safely, or is it a sign of a physical defect that requires a full panel replacement under the manufacturer's warranty?
