On Slack users channel, William Godoy suggested that this can be resolved if one launches Julia with:

Scaling of anisotropy

Daniel P. observed a factor of (1/S) difference between anisotropy strength in traditional linear spin wave calculations (as in SpinW) vs. SU(N) formalism. It appears that the SU(N) formalism is more correct, and an effective renormalization factor is necessary to make the SpinW result correct.

Update We've written a paper on this observation, https://arxiv.org/abs/2304.03874, currently under review. Sunny now incorporates the renormalization by default.
