Is this an issue with the LCD screen on the Nintendo Switch V2?

I noticed that there were vertical lines to the left of the screen. One line was reactive to the display, meaning it had variations in colors throughout gameplay. I never dropped my Nintendo Switch V2 and had barely touched it since 2020. I planned to look further into this when the entire screen displayed vertical lines throughout, along with a circle of discoloration.

After charging to 100%, the vertical lines to the left have resolved. However, the discoloration remains. What is interesting is that the coloration does not appear until after I power on the device from sleep. If I were to increase the brightness, the discoloration intensifies and remains significantly bright despite reducing the brightness afterwards.

What could be the cause of this?
