Depends on what you define as 'being worth it'? If you want to gain the maximum amount of xp while collecting from them, lvl5 is always best. If you mean profitability-wise, it would take approximately 40 hours on lvl5 with 3 totems and oracles before you break-even with the costs for upgrading. But this is when you did not fast-forward the upgrading process. If you do (because you do not want to waste 14 hours on upgrading which you could otherwise use to collect 14/1.4*13=130 Quantum Points per Sunny center) the upgrading costs will more than triple, taking almost 6 days before the building becomes profitable. Even on lvl0 with 0 totems and oracles, the building will become profitable after just 17 hours.

So, to recap: upgrading to lvl5 will be worth it if you want to gain some extra xp. Upgrading to lvl5 for only the duration of this event will NOT be worth it in terms of profitability.
