FH launch with crew 4 ?
(OP)
I noticed an exhaust plume appearing to get pushed away from the rocket, about 2 minutes in. Some interference from the 9 engines ? thoughts ?
another day in paradise, or is paradise one day closer ?

now the first stage is getting close to empty and shut down and over 200km high ... less optimum combustion ?

Well mixed stoichiometric RP1 and oxygen will burn nearly blue but that is only the case inside the combustion chamber.
Fuel rich RP1 and oxygen burns with soot and color.
The orange flames are the burning of the excess fuel from the gas generator portion of the engine.
The gas generator exhaust is vented on the outer side of the nozzles on the 8 perimeter engines.
When the excess fuel hits the oxygen in the air and the main plume (reheating it) it burns producing the orange flame as shown in the 8 outer flares close to the rocket. But the gas generator on the center engine is not exposed to the air yet.
As the 9 plumes merge and mix farther down some air get mixed in and the excess fuel from the
center engine creating the main flare in the center but it is spread out due the extra mixing.
The flares are not as pronounced at lower elevations because the main plume has not spread out to provide the relighting of the gas generator plume, it just stays a trail of black soot and disperses.
