I made some changes in the Calibrate_BLACK node and set the second value_2 to 1,0000 also, this remove the tint from the background complete and it don't make the background image darker no more.. also the Blending Factor can be set down to minimum and it give nice effect, you can pick the LIT and Shadow colors direct from the Material room and works so fine and more acurate.

Thank you BB again you really spare so much work for me doing it, especialy for animated work this is so excellent .. the rendering speed too
I have to make the HDR + light test to see how it come out but well I hope the AO pick up the nice color as usual.. have to test it while hot on the table! :)

somebody can make dinner for me? I am busy... just kidding..
