I don't know what "early" represents for you so cannot comment on that but my close to 10 year old 55 inch tv still doesn't have it.
Either way there's something about OLEDs that my eyes prefer, I cannot verbalize it. Maybe it's placebo :)

When you look at that, there are CNN artifacts in some of the TVs as early as 2 months and 4 months. That's early enough for me.
