This is not correct. There is a sizable subset of read heavy enterprise workloads where the economics of a QLC drive are compelling. Micron has already announced that their first QLC drives will focus on Enterprise, and that is where all the growth is. HDD still reigns supreme for read heavy enterprise workloads. QLC is the Edsel of NAND. The economics may look compelling on paper, but that is where it ends. It will flop in the enterprise, and later move in to consumer based products (promising "enterprise grade" technology). Secondly, can you explain what "quadrant located 3 bits per cell" means? I've never heard of it, and a quick google search didn't find anything either. I would suggest you google for X4, which is the technology created by M-Systems, later acquired by SanDisk. This technology is based on 3 bits per cell, with the "4th" bit of information encoded in geographic placement of the bits (in a cell and adjacent cells). Samsung, in litigation documents, admitted that this technology was worth billions. This technology is quietly at work in current WDC products.
