CERN is usually running experiments to validate ideas, confirm new hypotheses, in general push the boundaries. They wouldn't just go "let's do the same thing as last time - we've already got the results, but let's crank up the power to get a noise-level improvement in numbers accuracy".

I don't think anyone's trying to only get that level of improvement. And the LHC is the definition of cranking up the power.
