This issue looks more a moire problem caused by the image noise and the "resampling" done when applying the lens correction. Stacking several images in lighten/darken mode amplifies the effect.
If you apply strong noise reduction and some grain, the effect is diminished but not eliminated
If I recall correctly, the issue with DXO was banding due the vigneting component. It was jus concentrical circles, not this shapes
I just tried the noise reduction (100% for both color and luminance, with no detail). The bands were drastically reduced and in a different pattern. The only issue for me is I almost never use noise reduction, besides the default color noise reduction applied by automatically.
