Yes at the panel by dithering adjacent pixels at a very higher frame rate [ +FRC overdrive] it is additive color wise in nature likewise a 6 bit panel with [+hight frc] in 8 bit overdrive can display 8 bit color fine .
With [+frc ] (overdrive 8 bit mode if you will ) a 6 bit panel can display 8 bit color . At true native 10 bit panel in 10 bit display mode and likewise for a true 8 bit panel in 8 bit display mode smoother grey scale/color gradation will sometimes be apparent on *some test patterns but not ordinarily noticeable in pgm. viewing ..
I have a 2013 Sony LED w/overdrive panel it works fine you will never notice it. I only found out by getting the panel number from serv. menu and looking the panel specs up. Panel also shows smooth grey scale and color gradients on test patterns. IMO it's not an issue on the newest panels anymore.
OTOH HDMI chip bandwidth is a completely different thing and on it's own can certainly limit color bit depth vs frame rate .
most with some exceptions 4K TV's right now are 8 bit panels using [+high frc] true10 bit 4K panels are just now entering the supply chain in volume and will probably be reserved for premium models any 12 bit panels will likely be 10 bit +high frc overdrive panels .
Some Sony sets use LG and Samsung SPVA-2 LCD cells with Foxconn fabricated and assembled back lights as do the triluminous FALD Sony panels and maybe same with an occasional AUO cell. I believe the AUP panels mostly in W800/850B come as complete assys .
All the Sony W600B use Samsung cells and Foxconn back lights .The 9x/9.5x sets that can usually be either LGD,AUO or Samsung LCD Cells with Foxconn back lights /edge lights . 84" Sony uses a CMO panel , Sony 70" 8x AFAIK
uses Samsung SPVA-2 cell and Foxconn back light/edge light +high frc panel . Sony does not make TV panels .
