Ah here: the ff have reached 2500+ according to this but aren't GM:
- Lela Javakhishvili
- Almira Skripchenko
- Qin Kanying
- Svetlana Matveeva
- Polina Shuvalova
Since all the peaks are 2500-2502, I'm just gonna assume the time they got the peaks is the 1st time they got the peaks sooo...
- Lela Javakhishvili - 2500 in March 2010 at the age of 25
- Almira Skripchenko - 2501 in January 2003 at the age of 26
- Qin Kanying - 2501 in July 2000 at the age of 26
- Svetlana Matveeva - 2502 in January 2004 at the age of 34
- Polina Shuvalova - 2507 in August 2021 at the age of 20
These are all over 15 years of age and all after Judit Polgar became GM (and thus superWGM).
Conclusion: The superWGM list is, for now, the same as the female GM list.
Update: Ok so there are also females who obtained GM without reaching 2500+ like Peng Zhaoqin. I don't think this affects either the superWGM list or the female GM list. If anyone has any idea, then please let me know.
