You are absolutiley right.Banks need to know first that you are an HNI. They won't know not thru your Cibil but your TRV with them, spends on the card or the documents you would present to prove your annual income or salary etc. That's exactly what banks would need to upgrade your existing card or approve you their best one.
But given that OP have salary account with HDFC. So they have access to all his investment and spend habits. I totally get OP's comment that "infinia have lost its charm for me". Just find better RM first and move account to different branch. Or bargain with other bank than HDFC. Seems all corporate are stressing on acquiring new customers and not giving any thought on retaining current customers. Move with the flow and become new customer, and don't forget to take your investment account with you too.
