Ansel hdr 360 capture - Banding problems

Hey, I have some banding problems that shows on HDR 360 capture (the sky). I am using exponential fog (volumetric) and the sky is just a picture.

I am curious if someone else had the same problem or this is just a unique? Or if there is some workarounds on this. This is btw not your standard banding that you would get on photoshop after converting the bitdepth to 16 bit from 32. As you can notice that the banding has same intervals inbetween. If you zoom out on the 360 viewer, you can see it clearly.

Here is the link to the 360 viewer - https://kuula.co/edit/7PHHv

Cheerz!
