both inlets are lit differently. I upped the brightness to release any detail data in the right side inlet, nothing is there.
based on the key lighting on the left side of the car and nose, there's simulated light illumination from the left side of the virtual room.
Even the inner interior left inlet is illuminated more than the right.
I think its the Louvres though, based on how the car is lit externally. no light is simulated directly at the inlet itself, the light appears to be simulated slightly from behind but definitely on the left.
