The 100%/100% results do look much better than 75%/75%. Was the CMS adjustments optimized for each run, or were these measurements taken with the same set of TV settings?

I try to optimise settinhs for 75%/75% but the result is almost the same. Do I have to change anything in HCFR settings exept Rec.709/75%/75% when I measure colors? Generator parameters are Image area 100%, APL 18%, GDI, Display Triplets, Gray scale 0-255, disable video LUT. Pixel format YCbCr422, computer is connected to the receiver with HDMI, one monitor fullhd and one uhd tv samsung 7500hu. The tv is connected in receiver with HDMI.

no, your interior colors are undersaturated and the CMS controls can't be used to addsaturation. Try upping the color control to something like 55 and try again. (this seems to be common problem on more recent Samsungs)

btw - even with that problem your colorchecker dE00 avg/max is around 1/1.5 which is quite good.

I've been noticing that with their sets as far back as 2008. They always seem to struggle with the lower points for red and blue.
