Updating squeezebox firmware
In an 8-bit system the fractions are truncated, but in the Deep Color mode the fractions are preserved so the data delivered to the display is more accurate.Note Some AVRs and displays give only lip service to 12 bit 4:2:2 or Deep Color 4:4:4 -- accepting the format as input but then immediately stripping off some or all of the low order bits prior to actually using that video stream.If you want to add cheap 433 MHz devices like PT2622 remotes, contacts, sensors or wireless outlets and don’t know the correct values, you can start open HAB in debug mode, press the buttons on the original remote or act on the sensor.

I don't know why this would be necessary, other than perhaps to minimize HDMI handshaking issues with touchy A/V receivers or displays.
Deep Color does not make your blacks "blacker" or your reds "redder." The most you can get along those lines is a characteristic of your display, not of the disc or player.
Deep Color (which ought to be called "greater than 8-bit color") provides a finer gradation of shades between the colors encoded on the disc.
Some Deep Color displays only actually implement Deep Color if you are feeding them a 1080p/24fps video stream -- i.e., not 1080p/50 or 1080p/60.
The result of all of this is that sometimes the only way to know what format is best for the HDMI connection is simply to try them all and see.
