I don't usually either.. it's risky business lol
anyway, I don't mind sharing my calibrated HDR settings..
the calibrator spent 4 hours here one afternoon doing ISF Dark room, HDR standard and to a lesser extent, game mode.
Basic settings: 100,100,50,0,56,G2
Picture Mode: HDR Standard
Advanced settings: off,off,normal,off,off white bal: warm2: code val: 127: 1,0,1 254: 0,‐3,‐2 320: 2,‐2,4 386: 0,‐3,2 419: ‐2,1,1 451: ‐4,0,‐3467: ‐4,0,‐3 482: ‐6,0,‐4 498: ‐7,0,‐5 513: ‐10,0,‐8 529: ‐11,0,‐9 544: ‐12,0,‐11 560: ‐13,0,‐16 575: ‐13,0,‐16 591: ‐18,0,‐21 606: ‐19,0,‐23 622: ‐20,0,‐25 637:‐21,0,‐27 653: ‐22,0,‐30 668: ‐30,0,‐35
The problem w/ calibrating HDR on the LG set is that you can't calibrate from 70 to 100 brightness levels on the white balance. They use code values like the ones above, and they don't go past 668, so the full range of brightness can't be calibrated.
