yes, it's possible to get one from premium or ultimate summon. But if you check the summon rate for premium summon, you can see they are indeed very rare (the chance of getting an UR card from there is about 0.5%). I doubt it's much higher in ultimate summon.

I myself have gotten Caspiel from premium summon (and Sif from a "first time free"-attempt)
