Now this isn't really a massive issue in our opinion. Yes, it might make a difference to some people who are looking for a true 8-bit compatible display, but most regular users would never even notice any difference with panels using modern FRC mechanisms. In fact we saw no adverse affects of this technology when we reviewed some of these monitors either and neither did other review sites. I'm only bringing it up to offer full transparency and for those interested in the detail. I have also updated the relevant reviews with mention of this change.
Also, keep in mind that the same situation can be found when you consider the modern "10-bit" panels. LG.Display again list their new 24, 27 and 30" modules as being 10-bit, and you will see highly regarded manufacturers like NEC and Eizo (and others) refer to their displays as 10-bit. In fact, with the exception of a couple of very expensive models, these screens are all using panels which feature an 8-bit+AFRC colour depth, so again, not a true 10-bit! Some models don't even use an 8-bit+AFRC panel, but carry out the FRC at a hardware LUT level instead of on the panel side. So there's no difference there really.
