Not exactly. Be very careful when thinking about "city improvements", and be really clear whether you're dealing with happy faces (yellow) and content faces (red/pinkish). City improvements (temples, colluseums, and cathedrals) generate content faces. They turn unhappy people into content people. There is no spill over in this case. No matter how many of those you build, you wont have any effect unless there's already an unhappy person in the city to make content.
So if you have a city with nothing but happy and content people, building a cathedral wont do anything. Also miltary police (thanks for adding that TheNiceOne, I tend to forget about them sometimes) wont have any effect. Arguably though, you have to assume your city will continue to grow at some point, so you'll likely eventually make use of all city improvements that generate content faces. However, in the early game, you can overdo it. If you're keeping your cities down in the 3-5 range for maxing out population production (settlers, workers, and such), building more then a temple is probably a waste.
What TheNiceOne was correcting me on was the effect of happy faces. Those are not generated by city improvements. They are generated by luxury resources, entertainers, and the luxury slider.
I am, however, slightly confused, becuase I usually see that around half of my citizens are content, and if happy faces go first towards making content people happy, and then unhappy people content, you should see very few content citizens in lategame when you have marketplaces and numerous luxuries... Are you absolutely sure about this?
That's exactly the issue I was questioning too. Except in the opposite direction. That's been the trend I've seen as well. In a civ with lots of luxuries, you really shouldn't see many content citizens. Pretty much everyone should be either happy or unhappy. The gist of my post was that there are lots of things in the game that generate happy faces, but not nearly as many that generate content faces. Since you only really get use of happy faces if you have an equivalent number of content faces, alot of the time, those happy faces are wasted. Even assuming the correction TheNiceOne made is correct, then you're still really only getting half effect from your happy faces once you have more of them then (content faces - {initial content citizens by game difficulty]).
Are you sure you have that many content faces? Using either my info, or the modified formula, you shouldn't have more then 1 content face in a city with really high luxuries available to it.
Take a size 16 city in regent. You've got all the city improvements (6 content faces). You've got maxed luxuries and a marketplace (20 total happy faces - yeah!). By my calculation, you would start with 4 content citizens (the default on regent), and 12 unhappy citizens. Then the 6 content faces would be applied, making your total 10 content people and 6 unhappy people. Then the happy faces are applied, making thsoe 10 content faces happy, leaving you with 10 happy and 6 unhappy citizens.
By TheNiceOne's calculations, you'd start with 4 content citizens and 12 unhappy ones (same). You'd then apply your 6 content faces and end up with 10 content and 6 unhappy (same). You'd then apply the first 10 happy faces and turn those 10 content people to happy (10 happy, 6 unhappy). You'd then use the remaining 10 happy faces to turn 5 unhappy people first to content, then to happy, one at a time. End result would be 15 happy citizens and 1 unhappy.
In both cases, the number of content citizens is zero. If you happened to have an odd number or luxuries, you'd be left with one content citizen. But that's the most you'll have in a civilization with a really high amount of luxuries.
I'll go back and play with that game (I had a lot of cities that were very large and had tons of luxuries, so it's a great test). I'll let you know what I find out. I'm pretty sure the content citizens should be low no matter what. If you aren't getting that effect, you might want to check out the city in particular. It may be that you don't have a marketplce built, or you don't have attached luxury resources for some reason.
