kk650 kindly provided me a clip of the DVD, EE BD and HDTV to test.
BD ColourMatch'ed to DVD is really good; no need to do it with the HDTV, as it's quality is really high, that I'm thinking about using it directly, or apply its chroma over the BD luma...
Now I'm really tired, going to sleep; tomorrow I'll continue to test further, and post some result here.
