Yes it can.
If I take a 1024 x 1024 x 8 monochrome image, I can apply error
feedback and reduce it to 1024 x 1024 x 1 using error feedback.
I have taken 1 MB of data, and reduced it to 128 kB.
If that doesn't fit the definition of a 1-bit color-depth, I don't know
what does.
There will be no posterization.
