The PQ EOTF tracking on the LG UR9000 is decent. All content is overbrightened in very dark scenes but then is too dark for the rest of its EOTF tracking. Content mastered at 600 and 1000 nits hard clips when the TV reaches its peak brightness, leading to a loss of bright detail, although this TV doesn’t show any truly bright detail anyway as it’s just simply not bright enough. For content mastered at 4000 nits, a slow roll-off preserves details well.
The graph above is with local dimming set to ‘Off’; here’s what the PQ EOTF tracking looks like with local dimming set to ‘High’. It’s a bit more accurate than with local dimming disabled, but unfortunately, it comes at the expense of massive blooming and unpleasant lighting zone transitions.
