Yes.
Burn-in is a real problem [0], especially for OLEDs last I checked.
LED backlights wear out, I've personally helped multiple people replace them in external monitors and laptops over the years.
And they're obviously more fragile and exposed to the elements than a GPU within a case.

What difference does it make? You do realize kids are a real factor, they exist, are rather common actually. And these days gaming has become just as popular among adults too.
It's as if everyone forgot the rash of broken displays when the wii came out... surely those people appreciated not having to pay for a GPU too when replacing those displays.

Do they?
In my experience they both last forever until you decide to upgrade to better specs. And in that case it's quite likely you upgrade both together.
Displays don't really "wear out" these days in normal usage.
Although I guess I'm not really sure why you say they're a target for thrown handheld controllers ha... are you speaking about yourself or about kids...?
