RGB is white balance the other controls are CMS granted they probably don't work well but they are there. My calibrator says HDR for external sources can be substantially improved with a calibration.
If HDR clipping is your main criteria then OLED may not be for you.

You have a B6? If you have a B6 (cause on C6 and E6/G6 the black seems to work on another way) and a movie like PAN (Sun scenes), Pacific Rim (Scenes with so much light), The Revenant (Sun scenes) or PS4 with HDR on Uncharted 4, test this:
Put Black Level to High, down by 2 points the Brightness to have back the pure black, now compare it to black level low with Brightness 50, the details you're losing by using Black Level to Low is INSANE, using @mascior
HDR patterns i've discovered that, dont know why but Black Level is directly vinculated to Colour Clipping, by setting it to High the clipping changes from 500/600 to 1600nits
! But using the black clipping test you see that you lose from 0 to 1,5% on black level, lot's of movie scenes uses that blacks, so it is annoying, thats why i wanted to know if there was any way to force the TV to change his Gamma level on HDR, that or LG has to make a firmware to let us use that contrast that Dynamic Contrast use, but only for black, because use Dynamic Contrast creates clipping too
As it is right now, seems like LG just want to force everyone to buy their 2017 series that will probably have all this changed, which is a shame
People with professional calibration can test the black level thing without any fear
, it does not alter any colour, just at what level it clips
