the exactness of happiness

So how exact does a desire need to be? Do we need exact fullfillment? i.e. I want a chocolate ice cream with seventeen cherries, a whipped like topping, and nuts or would merely receiving one make you happy? I know Dan Gilbert and others theories less is more, repetition etc, but let’s imagine the brain has pattern recognition that only perceives patterns at a certian scale. So for instance if our sense of taste was low-res then the number of things that would make us happy would be more and if our tastes are more exacting then we might dislike more things or perhaps experience them as more naunced and hence more flavorfull? But my point is, the brain can tease patterns out of anything, does that maker the brain happy? perhaps not all the time, but what is the resolution of your senses? after 15 fps we can’t tell the difference between if something is moving on a tv or not (if you get up to 60 fps it doesn’t really matter either). I’ve lost my original thought, but let’s imagine life as experiencable objects that you can savor, what are the best ones? to what scale do their propoerties make you happy?
