Looking at the images, it’s possible that it’s the fog rendering differently… i.e thicker fog, or more scattering. Try removing it and do a render. I’ve had issues with Ultra Dynamic Sky not rendering the global volumetric fog material correctly when UDS was set to cinematic/offline mode. (I fixed it by either disabling the ‘use global volumetric fog’ tick box or changing the UDS project mode to ‘Game/real time’)
