SUCCESS!

Colors are correct!
Software decoding now has multithreading option that works!

I was able to fully decode the two 40Mbps clips I tried.

My setup: Intel Haswell i3 NUC

--- STEPS ---
- Use the Nov. 20 Generic build here (x64): http://sources.openelec.tv/tmp/image/Ope...r16406.tar

- Create autostart.sh

echo "#!/bin/sh" > /storage/.config/autostart.sh && chmod +x /storage/.config/autostart.sh

- Edit autostart.sh to include RGB and IR fixes

nano /storage/.config/autostart.sh

Paste inside autostart.sh file

# RGB fix
DISPLAY=:0 xrandr --output HDMI1 --set "Broadcast RGB" "Full"

# IR fix
modprobe -r nuvoton_cir
echo "auto" > /sys/bus/acpi/devices/NTN0530\:00/physical_node/resources
modprobe nuvoton_cir

In XBMC
1. Settings->Video
- Enable "Expert" level at the bottom of the left-hand menu

2. Settings->Video->Playback
- Disable VAAPI
- Enable "Frame Multi Threaded Decoding"

3. Settings->System
- Enable "Use limited colour range (16-235)"



That's it!

Video calibration tests all pass and the i3 is able to handle at least 40Mbps MKV files with software decoding (I've only tried two of them, and nothing of higher bitrate). But, for comparison, one of the 40Mbps files would only play at 12fps before Multi Threaded Decoding, now it plays at 24fps!

A great big thank you to lmyllari for all the hard work and dedication in researching these issues and helping everyone understand them!
