Well, from The Bottle Episode, it's not absolutely clear whether or not the Earth-Prime memories are gone. But Alex really seems troubled about working for Luthor. And there were doppelgangers. Two Als, a new Selena, and a whole bunch of Brainiac Fives. Meanwhile, everyone else is treated like the same people from Earth-38. William Dey's motivation for joining Catco was changed from suspecting Rojas to suspecting Luthor and apparently Rip Roar didn't happen. But that's still a Flashpoint-esque kind of change. And Lena woke up remembering only Earth-38 like Kara, with Lex explaining that his deal with the Monitor allowed Lena to remain intact, so Lena is the same Earth-38 character we came to know and shouldn't even have an Earth-Prime article.
