Bad News guys...it's has crazy near black gamma flickering hopefully it will be addressed with next firmware.

This looks faulty - NVIDIA tests for flickering and the likes, and if any is detected, monitor does NOT get G-Sync certification. Which is one of the reasons I always bought the ones with certification from them (usually just G-Sync compatible) and never had any vrr flicker of any kind then. And this model has G-Sync Ultimate, hence it seems to be some fault of that particular unit.
