"It makes no assumption about what happens downstream, let alone assumptions about the DAC."I'm not saying it does.... I'm only saying it's needed to fully realize the benefits of dither. Without filtering in the DAC, a dithered signal at half the LSB will be represented as a random toggling of the LSB between zero and one. With filtering, that same signal would be a lot closer to half the LSB, as how the signal was originally.
