I don't think that's right...
It's just white with black. The "Is this it?" image you posted shows there's a normal camo underneath the white and black. If you look at the top-down view you can make out the standard splinter camo under neath the winter camo.
Another point: It's not very common for the LW to use black paint. Almost never. Probably it is some shade of Schwarzgrun or a dark green. The image you posted had the contrast turned up way high, so I wouldn't be surprised if it was supposed to be dark green but just looked black.
I'd like to see it without the solid white with black stripes. I'd like to see it as a standard camo with the temporary winter camo painted on top of it.
You asked a few posts below: It would probably be lichtblau underneath. Most winter camo left the undersides as-is. Winter camo was protection from being spotted from above. Undersides were already painted to help prevent detection from below, painting over that would be counter-productive.
