With AOD this is the best you'll get for now, Sony did some weird stuff with AOD in overlays on stock and we had to do some kernel hacks just to lower the brightness a bit, also about refresh rate just use the QS tile, i will remove the settings options since they overlap with the tile and Smooth display never even worked for me or others so i've removed it as well.Almost perfect os,but still some bug.AOD has a wired brightness and will not auto disable when you put phone in the pocket.Some times freshrate will stuck at 60hz.Buggy launcher and I think it's rom's bug.
