Thanks! Not sure if you’re aware but Lunar also has XDR Brightness: https://lunar.fyi/#xdr
In fact the feature landed in Lunar before Vivid launched and it uses a different approach that increases the brightness for the whole system instead of only for what’s behind an overlay like Vivid does (although the overlay also has its own advantages like being able to only increase brightness for a single window etc. )
It can be activated in the same way as Vivid: increase brightness over 100%
Yep, that was why I installed Lunar as well. I was evaluating the various options, between Vivid, Lunar and BetterDummy since they all have the XDR feature.
