After operating the LED, I assume that we should get some radiation
above 0K with black body signature.

Sure, as the wall gets heated. by LEd ( I hope for a power LED ).
But as LED is involved. be aware of BB radiation
is radiation at radiative thermodynamic equilibrium.

What means that the LED would keep the enclosure
from the reaching radiative equilibrium.

That means e.g. the blue light intensity
in case of blue or white LED
would be MUCH higher than the equilibrium intensity
for given temperature.
