Anyone know how to adjust the brightness of this display using the MacBook Pro Touchbar?

In the past, I was able to adjust my display using a modifier key, but I've tried many combinations and I can only get the touchbar to control the MBP's screen brightness.

    Anton, thanks for your answer.
    The key is discovering the 'more' panel hidden under the "<" caret, where the discrete brightness buttons are hidden. The 'Control' key indeed works on those buttons.
    I actually spoke at length with both Apple and LG support. Apple confirmed this is a known issue (as of writing) and also offered the acceptable solution you also suggested until they get around to a more elegant software fix.

    I can see a future where the whole keyboard is an oled touchpad that changes on context. Then we could having a separate slider for each monitor!

  • Use control modifier key and use brightness buttons (not slider) in touch bar.

  • Go to System Preferences → Displays. There you will find a software brightness slider.

    Would certainly be useful to have this in the Touch Bar, though.
