Of course I would never use a shot like that to judge correct fleshtones because they are too many unknown factors in play like lighting and the grading GL and co chose to apply to that scene. That said, to my eyes the second shot, that uses my current settings, look fairly accurate to me. C3PO looks gold, R2D2 looks blue, the sky looks the correct shade of blue, so it would follow that the fleshtones should be fairly accurate as well.
It was these shots between leia and darth vader on tantive IV though where I really decided what settings I would most likely use for overall fleshtones. These screencaps below are using my current settings, just like the second screencap you posted above:
