A surprising result. But probably true. With a zero driving impedance the driving voltage is maintained no matter what the secondary load is. And when the driving impedance is zero, you can remove the core entirely and the performance will be the same.The primary inductance doesn't have to be much at all to prevent a complete short at low frequencies and so the core is not doing anything useful to a zero driving impedance. All the core ever does is support low frequencies in transferring the energy to the secondary by raising the inductance for the low frequencies for the case when the driving impedance is higher than zero.
Since the core has no effect, it is acting like an air core transformer all the way. And there is no distortion in air core mutual inductance.
