There is a long series of photos and text after the final episode that explains most of the fictionalized parts of the series and the real life outcome for most of the major players. IMHO the New Yorker piece has the perspective of a Soviet history expert who is extremely unhappy that their version of what is important to be shown was not shown or not accurately portrayed, watch Chernobyl for entertainment and a little enlightenment, but not for 100% fidelity to history. I can give a small example of what people complained about (spoiler like New Yorker piece). A helicopter crash in the TV series for which one can also view the historical footage - the historical footage is inexplicable - there's no obvious reason for it to happen but the TV show changes it so it has visible, plausible reasons to the viewer.
