I rendered as an EXR sequence with the DWAA codec in Eevee. It could have something to do with that or it might just be my monitor, I'm not sure.

This is banding. It's common with 8-bit colour output and subtle gradients. Either enable dithering in post-processing or output to a 16-bit format (noting that monitors generally can't display all these colours and so you'll still see banding until you apply dithering).

This is part of your EXR after converting to 8-bit with dithering applied in GIMP - banding is much reduced:

  • $\begingroup$ @Nick I rendered it with a full colour depth (^see edit to original post^) so surely because it is a 32 bit colour depth it would be more than sufficient to avoid banding? Might be very wrong, just thought I'd ask. $\endgroup$
