True enough, but a late-game save with 8 cities, dozens of wonders and buildings, world fair, and various other complexities probably isn't the best place to start for analysis 
But there are also UI design issues to be solved or at least clarified; we need to know what we think *should* be displayed before changing the code too much.
As long as city state culture is washed through city-level % modifiers, then it is going to be very confusing to display culture from city states at the empire level. The two best solutions IMO are either to remove the ability of % modifiers to affect city state income, or to not display city state culture at the empire level, and instead display it only in the city screen and in the city state screen for each individual city state.
