Single OLED takes a dive within a year which is why Apple went with Tandem OLED which mitigates some of the weaknesses but it costs more, particularly as the screen gets bigger.
LCD most certainly has color degradation. About 8 or 9 years ago I was able to compare a almost brand new surface pro 5 to my 3 year old one. I was shaken by the difference in difference.
Don't forget the OLED stutter on slow moving scenes because of sample-and-hold. It's why motion interpolation (soap opera effect) exists. I can't watch OLEDs because of it. Looks horrible.
The soap opera effect has nothing to do with OLEDS.
It is to do with higher framerates on movies than we are used to, making movies look like cheaper filmed tv shows. Not a specific display technology working differently.
Peter Jackson famously had this issue when trying to show The Hobbit in 48fps, and that was in projectors in theaters.
Notice on the wikipedia page for 'Soap Opera Effect' it doesn't mention the term OLED once.

The Gamer Boys are in denial about the inherent weaknesses of single OLED see the comment section.

I have the original 5k Studio Display, and it's been worth every penny.
