Hmm is that so? To encode 4 bits you need 16 distinct voltage levels, no?

In that sense the L in QLC is is not a "distinct voltage level" but more than that. If you only had 4, say, 0, 0.33, 0.66 and 1, you could encode 2 bits. Just like the old NeXT monochrome looked good with 2-bit graphics, showing black, white, light grey, and dark grey.
