Check the "Polynomial Interpolators for High-Quality Resampling of Oversampled Audio" document for a very good treatment of the issue. I believe that the SNR value in the Summary on p 60 gives a good approximate of the amount of aliasing it introduces, it seems to ballpark with what I'm seeing in the spectrogram with Matlab.

2.3 Oversampled sample source As depicted in [1] and [2], polynomial interpolator performances are dramatically improved on oversampled input data, where only a small part of the full spectrum is occupied. This gives a much flatter passband and very reduced lobes. The more oversampled, the better the performances.
