Doesn't look like it.
Cheryl at Balloon-Juice:
I assume the white clouds in box's clip are steam from masses of water cooling all over the stuff downstream from the rocket plume. But it might be from the combustion also too.
But it's not N2O4 if Cheryl is right.
Cheers,

The main evidence comes from North Korea in photos and bombastic statements. They fake stuff, including photographs, so the analysts also test the photos for enhancement. But there is much we can learn even from faked photos. These three show clearly that it is liquid-fueled. The orange clouds are distinctively dinitrogen tetraoxide, the oxidant for liquid-fueled missiles.
