Banding / Striping with SILK PLA Filament

Recently started trying Silk PLA filaments for the first time. This was printed with Eryonone Silk Rainbow PLA. The glossy sheen seems to come out well, but there is this odd banding/striping as the hue changes sometimes.

I've printed with several Eryone matte filaments and I haven't seen this. Could this be a defect with the filament, or do my settings for silk still need some work?
