As I understand it, for the burn-in you can just turn the display off. It was not always that way because old CRT monitors take a while to turn back on so it was annoying.
I have two LCD monitors and a CRT monitor in use right now. The CRT is a lot faster in turning on, though it did stop displaying the color red for a bit, though I did fix that by unplugging it and letting the capacitors drain so whatever.
They are very much still kinda necessary. They prevent burn-in, which is still a possible issue on certain types of displays (like OLEDs).
Then again, even back in the hay day of screensavers you could have simply turned the monitor off and left the PC on. 🤷♂️

My modern LCD takes eons longer to turn on than any of the CRTs I’ve used.

Meh. Who needs red.
