Brightness = black level
Contrast = white level
OLED light = panel background light level (Sony is about the only one that calls this "brightness")
For SDR content you can set brightness and contrast as needed to produce the best detail with slides which contain a range of black and white levels.
For HDR and DV the source sends that info to the TV so the TV just needs to be set at the optimum point to receive that input, which on the 7's is contrast 100, brightness 50.
I think we are in agreement that "Cinema (Home)" is "brighter" than "Cinema (User)". "Cinema (Home)" is intended for use in bright rooms, and "Cinema (User)" for med bright to darker rooms. The problem I have with "(Home)" is that they cranked up every IRE level - which improved dark scene detail - but also blows out the mid-to-high IRE levels - making normally lit content look harsh and unnatural.
With the Calman DV custom workflow - ( specific to the 7 series OLED's, and the "Cinema (User)" picture mode ) - the goal was to flatten out the EOTF response curve to follow Gamma 2.2, and also balance the IRE levels. That way the lower IRE levels got the needed boost to center, and the mid-to-upper levels were brought down to center - just like SDR - but with the benefits of wide color and dynamic lighting/spectral highlights. The "pop" was no longer embellished, and the harsh picture characteristics - "(Home)" - were also put to rest.
Gamma 2.2 is best in a med to dark room, so it does depend on your viewing environment whether you will see all the dark details, even if you use my settings. If your viewing room is bright, the "(Home)" picture mode may be the only way to go.
Finally, there's always the dreaded panel variance conundrum, which will impact your viewing experience as much as any of these other factors.
