I got a similar impression from the XRD spectra, but I don't think it's correct to focus on the shifts. That could easily be a minor calibration issue. The biggest difference I see is in the peak around 44 degrees, which is very pronounced in the original work and much weaker in this work.

There are strong similarities between the XRD patterns, but considering the theoretical paper yesterday about selective site substitution being necessary to achieve superconductivity, it's reasonable to suspect that these "minor" differences may be critical.
