Question Is this weird stain on my MacBook Pro display repairable ?

[noalimai]

I have the last 16" Macbook Pro with an M3 Max chip. Unfortunately, I spilled wine onto my keyboard and instantly a weird stain appeared on the left corner of the display. Do you know which component has been damaged ? Is it repairable or do I have to buy a new entier display ???

I have another question too, the keyboard is also sticking and the backlight is blocked at some places. Is it cleanable or do I have to buy a new keyboard ???
Here are some pictures.

When you lightly press on the discolored area on screen does it change or disappear? In regard to your keyboard, check with the manufacturer's website, or google it, to see if the keys on the keyboard are removable. If they are, remove the sticky keys, wine has sugar in it that is what is probably causing the stickiness, carefully remove the keys using a flat head screwdriver. Never spray a cleaner directly on to the laptop. You can spray the cleaner lightly on to a cloth and clean under the removed keys to see if it helps.
