I have a zero balance account in ICICI which I opened online in Aug-23 by depositing 95,000 as opening balance. This offer was running back then, in the mid of Aug-24, ICICI upgraded my account to privilege banking account automatically, my TRV with ICICI is less than 50K. I feel that if you open bank account, they may automatically upgrade it to privilege banking account. However, I didn't feel anything special so far while operating the account. Maybe in branch banking experience would be different but I rarely need to visit branch.
