I see those aft stream markings as caused by the Falcon having the engines running at idle while on a planet. They flow down the curved hull like heavy smoke or water would flow without any other motion involved. If the Falcon was in motion the streaks would be along the movement axis.
I figured the Falcon spent a fair amount of time planetside between cargo runs, Han kept the systems up in case he needed to leave quickly so the six exhaust radiators vented the built up heat and gasses during that time. Most of the weathering and rust stains across it's hull also flow downhill along the hull curve, which could only happen in a gravity environment too.
However, the aft markings do flow differently between the two different models. They actually streak straight back on the 5 footer...
