If it was the case that simply atomized fuel was exiting the prechamber there would be no carbon from combustion in the prechamber.

I don't know the exact word used to describe the ignited, exploding and expanded fire ball that first exists in the prechamber that ultimately enters the space above the piston, but it is much more than simply atomized fuel.
