If only... That is the problem.
You are so eager to be right, you are totally
off the tracks and probably tap yourself on the back,
marveling at your own magnificence...
Here is a scan from my BR's user manual:
HDMI Deep Colour (HDMI 1)
– To select Deep Colour modes for the
HDMI 1 output. Deep Colour is an OPTION for some TVs or projectors
that feature HDMI v1.3 or higher input.
Normally, each pixel of the video image is transmitted using 24-bit data
(8-bit per channel for R, G, B or Y, Cb, Cr). If Deep Colour is supported
on your TV each pixel of the video image can be transmitted using 30-bit
(10-bit per channel) or 36-bit (12-bit per channel) data. The increased bit
depth should result in smoother colour transitions and better gradients
for better picture quality.
For BD discs with native deep colour on them the extra information will
be passed to the TV. For up-scaled content such as DVDs the deep colour
output will be interpolated but can still result in a smoother picture. The
dithering/limiting options allow discs with deep colour content to be sent
to TVs with limited deep colour support.
Dithering is a way to softly limit any extra colour information in the source
material that the display cannot handle by adding ‘noise’ to prevent an
abrupt step in the levels.
The available options are:
36 Bits
– Always use the maximum 36-bit per pixel Deep Colour mode
for the output.
30 Bits (Dithered)
– Use the 30-bit per pixel Deep Colour mode with
dithering of any over 30 bit content.
30 Bits
– Use the 30-bit per pixel Deep Colour mode and hard limit
output at 8 bits per colour.
Off (Dithered)
– Do not use Deep Colour, dithering any over 24 bit
content.
Off (default)
– Do not use Deep Colour, hard limit output at 8 bits per
colour.
Toy Story 3 uses Deep Color.
Make of it what you want.
Keep your player and TV at 24 bit, enjoy the original
Bluray specs and have a great time watching movies
as you like them.
