Does ktc m27p20 pro have a 10bit+FRC matrix?

[BOLNICHKA399]

Again, I’m with my monitor), according to its characteristics, it has a bit depth of 8bit+FRC, in the end we get fake 10bit. But in the latest monitor firmware it became possible to enable 12-bit support at 120Hz. But how did this become possible? Indeed, in my understanding, in order to get 12 bits from FRC, the matrix must be able to output honest 10 bits, but before it had honest 8 bits due to a technical limitation of the matrix. Or is there an advanced version of FRC that can produce 12 false bits on an 8-bit matrix?
