OK, here it is - i've applied your passthrough patch to 4.4-rc kernel. Previously i had Limited Range set in Kodi - with this setting and passthrough patch everything "was nearly ok" with 4.3 kernel and with 4.4 with my modified patch, as described if first sentence.
After reboot (so in 4.4-rc3 with your new patch) colours in Kodi were washed-out (much too bright). Playing video made it no better. So i disabled Limited Range in Kodi and colours returned to normal good brightness. But even more - first time with calibration patterns i've everything 100% as it should be in theory with limited range - everything below 16 was black and whites over 235 are white (not over 254 as it was before).
