As you will likely be funding this yourself, understand that what you seek is a very pricey undertaking.

What we know: Your upper unit or "lid" is one sealed assembly. Should any component of that assembly fail or suffer damage, even cosmetic, the entire assembly must be replaced. Individual components of the assembly cannot be separated serviced or replaced.

We are not Apple and cannot make cost estimates, but other forum users posting their experiences here say the display assembly service starts about US$550 and goes up with screen size. That was before the current steep jump in prices for tech components.

You can pay for the repair, buy a new computer, or live with it.

Remember that, as we are your fellow end users and not Apple, we cannot give you official or binding answers here. As wisely recommended by my colleagues here, have Apple evaluate to get an official answer.

Wear and tear such as scratches on the exterior is not covered under any warranty. It will not be replaced and any repairs you desire to the case you will be charged for, both parts and labor.
