I'd treat this as an opening, not a trap. Gather your colleagues and draw up an explicit list, the actions you need leadership to take, and the support you need to act on the rest yourselves. Be specific about what would genuinely improve the environment, not what would simply move a number.
Then build a dashboard to track progress against it, visibly.
This resolves the dilemma either way. If leadership follows through, the scores rise because the conditions earned it. The only legitimate way for them to rise. If they don't, you'll have a clear record of exactly where the gap sits, and who was accountable for closing it. Either outcome leaves you stronger than simply being told to produce a better number.
