Should I replace the top screen or nah?

So, I've had this New 2ds XL for about 2 years now and I've bought it with these scratches.

I was thinking about replacing the top screen but im not veryyy skilled in stuff like that.

I once fixed a little problem my boyfriend had with his 3ds XL, but thats it.

I'm not really sure if I should replace it because I've heard the New 2ds XL is difficult to work with.

Should I just leave it like that? Lemme know 🙂
