As a copyright holder, you can license your code under many as many
different licenses as you like.  Commercial, closed source licensing
is not precluded by releasing code under an Open Source license.

Why should a dithering algorithm be device specific?

If you'd like to discuss legal implications, we can certainly do that.
I'm not a lawyer, but, I've seen one on TV.

Probably the best way to impress VA/Corel is to release the code.  The
code becomes your resume.

Thanks.  I can't speak for the group, but, I'd rather not see the code
until it's free.  If, for any reason, the code never becomes free, there's
always the possibility that we could be influenced by ideas in the code.
It's probably better for us not to see it at all.
