Thank you for your explanation. Do I understand correctly, that this idea wouldnt work because you either end up with the same quality, but bigger files or with the same file size, but worse quality? I had this idea that you could increase the amount of black colors a monitor could display if you combine 4 pixels. Having 3 black, and one of them "one bit" less black. This way you could have a more fine grained black-white transition. I thought a "log" video might be able to contain the information to allow this without to much overhead.
