Smaller machines will tend lower from what i have seen. If you give a large enough pool of scientists access to significant compute resources, they will generally figure out how to saturate them. Also, scientific teams often can't pay top software engineers. Lots of hardware is a way to compensate for inefficient code. If Lumi is underutilized to such an extent someone is funking up.
There is of course no commercial use case for these computers. That's not the point of these machines.
