Lunar developer here, I also use this trick to showcase Lunar's XDR Brightness: https://lunar.fyi/#xdr https://lunar.fyi/#xdr (which by the way, was the first app to get this feature before Vivid took over with clever Twitter marketing) Some people will worry about battery and display longevity in the comments so I'll also leave some notes I wrote on this: https://lunar.fyi/faq#xdr-safe https://lunar.fyi/faq#xdr-safe TLDR: yes, battery and LED lifetime will take a hit. It's a normal consequence of driving the LEDs to a higher voltage which uses more battery power and creates more LED heat. macOS has an ABL (automatic brightness limiter) internally that will forcefully limit the voltage based on the amount of white pixels on the screen, and based on the generated heat. That ABL works at a lower level and cannot be bypassed by apps like Lunar or Vivid. Also for the people wondering about BTT, look for the "Toggle super brightness" action.
