That is an issue. People don't understand what bit-depth reduction sounds like. That doesn't change the fact that the hiss is the difference. That is the quantization noise floor, and the primary artifact of the conversion. Rather than try to goad people into thinking that there is no difference, it is better to educate them on what the difference actually is (or could be). From there an honest interaction can be had regarding the potential perception of these differences. Quite simply, just because some people are misinformed about what qualitative effect is occurring, that does not discount the fact that there is a qualitative effect occurring.
