CPU/GPU Discrepancy

Is there a specific feature limitation to the Arnold GPU engine that would cause this distinct difference in renders?

Identical render settings aside from being CPU/GPU. Also see attached shader network.

Geometry setup is just a deformed sphere with a bunch of smaller emissive spheres inside.

Lighting is a single Arnold Sky/HDR with no fancy settings.

Is this fixed? I'm having the same discrepancy in Arnold 6.2 MtoA 4.2.1
