Now that I have re re read your post , and looked at the EWD for the Reverse lamps I will hazzard a guess
More like I will try to theorize I guess
The backup lamps also have a camera that powers from the same circuit
Also a feed goes to the radio (dont know why)
Power comes from the lighting module when reverse is activated, also When the key is shut off,when in park.
Then the lighting module powers the lamps, runs a timer, then kills the lights after a preset time.
There is likely a residual voltage stored in the camera and radio circuit that discharges through the incandescents, but because they need quite a bit of current to light you dont see it.
However, the LEDS use so little current and are not a low resistance path to ground so may continue to illuminate dimly as a result of said condition of the backflow of resdiual current
almost like flyback voltage if you will.The incandescent would bleed the voltage down without you noticing probably
My GTO has a hefty stereo system.
It has a 1 farad cap next to the subwoofer hooked directly to B+
If I unhook the battery for the car , with the door open, dome light on, the LED dome light stays lit, and slowly dims for about 15 seconds and then goes out
You pickin up what I am puttin down?
Dome light hooked to a capacitance that is charge, slowly discharges through t he LED
It would dim much quicker with and incandescent,
