The problem is that the axsf file does contain the displaced positions¹ but xcrysden does not display them. It is an xcrysden bug and I recommed you ask to the xcrysden mailing list², but there is a chance Tone will read this message here and he may have an answer. [1] Even if in DFPT the atoms are not physically displaced, we can find the displacement patters along which they would move (with amplitude a function of the temperature), that's what is saved in the axsf file, the displacement length set to an arbitrary value.
