Many people have claimed they are but I don't see any evidence to prove this.
I have a mini1 and have played with the parameters a bit. By doing this I have managed to repeatably achieve 6m/s ascent (mini2 is set to 5m/s max ascent). I've also increased the max allowable tilt to 40deg and acceleration is noticably swifter, while the drone doesn't lose altitude as a result of the increased tilt. I've not managed to hit 16m/s but have also noticed that the full 40deg of tilt only gets used during initial acceleration and the tilt gets backed off to 15-20deg once going faster (up around 8m/s and faster) If the firmware used the available tilt a bit more I'm sure the mini1 could hit at least 16m/s.
In short, a few firmware mods to the mini1 make it perform just as well as the mini2 (with the exception of top end speed).
