The "bit-depth" (Color-Depth) of the actual panel
in the KS9000 is fixed
. You cannot change this - it's a 10-bit panel.
Now most currently available content
(e.g. SDR content, Games, etc.) is usually mastered at 8-bit
Most HDR content
is mastered at 10-bit (i.e. the "10" in HDR10 stands for 10-bit). Dolby Vision content can
, on the other hand, be mastered with a 12-bit Color Depth (if they so choose).
Now what you have to understand is that any
of the above content can be sent to the TV as an 8-, 10-, or even 12-bit signal
. Content that is sent to the TV as an 8-bit signal will be "up
-converted" to 10-bit in the TV. Whereas content that is sent as a 12-bit signal will be "down
-converted" to 10-bit in the TV.
Note: Although your TV panel is 10-bit, it will still except and process a 12-bit signal
. There currently are no TVs available with 12-bit panel, not a single one.
For instance, UHD HDR Blu-ray discs are all mastered with a Color Depth of 10-bit. However, you can send that content from the player to the TV in a 12-bit "wrapper" or "container". The TV will simply down-converted it back to 10-bit.
Now to answer your question about "color banding", the banding you are seeing could simply be caused by "compression artifacts" (from the signal being overly compressed) or could actually be present in the original source content. If this is the case, there's not much you can do about it. The higher quality the source, the less likely you are to see these.
They can also be caused by having incorrect settings
on your TV (you can always go through my "Picture Settings Guide
" linked to in my signature below).
