Well the data I've linked to is for the first type of rolling resistance, hysteresis losses between tube/tire/road. And yes, higher pressure yields lower crr on rollers.
What the link doesn't address is losses from varied surfaces.
Below you'll see a graph from some testing, though not completely dispositive of the issue, it shows the trend I've seen in the past:
