OP here - So the way we rendering this we are using the braille characters that are available in the character set on the terminal.

That's interesting but not clear at all in the readme. Do you choose specific characters for their shade/coverage of each dithering cell?

ah yes, I went with the braille characters ascii values between 32 and 95.
