Computer generated hologram question

Had an interesting question come up today, no time to analyze just yet.
Consider a computer-generated hologram (CGH) null corrector with a
positive EFL forming a real, deliberately aberrated axial focus at
0.6328µm.
Now change the playback wavelength to doubled YAG at 0.532µm.
When expressed in wavelengths, is the CGH wavefront error the same at
0.532µ as it is at 0.6328µm?
In "all" my spare time I want to do the analysis to see for myself, but
thought until then maybe someone here had already been there dun that
and knew the answer right off.
Thanks,
Mike
