IPv4 address depletion affects the ISP community first, and then larger enterprises who will need to continue growing. This is why 32% and 29% of IT staff in these communities see IPv4 depletion as a "huge concern".

That's actually remarkably high level of awareness for a problem which is still 3 to 4 years out, and it is only going to increase over time. Whether small and medium IT staff need to worry much about IPv4 depletion is predicated on whether their organization is going to be growing and need public address space as an result.
