Earth-S is different - it was clear cut that all Fawcett adventures, as well as the later stories featuring Fawcett characters, took place on Earth-S. But for Quality, it's part Earth-One, part Earth-Two, part Earth-X (and those were the same as Earth-Two, AFAIK), part Earth-S, and even part Earth-Twelve.

"First DC appearance" is simply incorrect for New Earth. Because that version in All-Star Squadron is the Earth-Two version that later moved to Earth-X. First appearance for the New Earth version would have to be first post-Crisis appearance.
