If you got Mayuri’s ending…​

Then you didn’t get any of the true ending flags (because you didn’t respond to Kurisu’s "Did you write it?" email with "scientist")

If you got Kurisu’s ending…​

Then you got some, but not all, of the true ending flags

If you got the true ending…​

Then you got all of the true ending flags.
