Statistical significance is about whether an effect can reliably be said to have been measured at all; it's not about whether or not the effect itself would be significant in the sense of moving some other needle.
The ~5% improvement reported here might just be an artefact of the data collection or random variation, rather than a consistent repeatable change.
