I find myself going back and forth between "bright" and "normal" (mostly normal though) on my TCL 55R617 in the "General" TV settings. I think I have brighter, bright, normal, dark, and darker available to me as options. There are some courses, such as the official Sawgrass course using its default settings, in which there's an underlying hint of darkness, where I go "bright" on my general brightness settings and it gets the game to look right again.
I'm not complaining about it as I can remedy my personal preference on this, but I was just curious to see how many others make a similar, global brightness adjustment with various courses?
