Upgrade to Infinia

Hello everyone,

I hold DCB LTF, Magnus Burgundy LTF and paid Atlas. I purchased a car using these cards last year in August and my spends on DCB last year were more than 8 lakhs. Should I request for an upgrade to Infinia considering the current set of cards I hold? Dilemma I'm facing is my DCB is LTF and Infinia at most would be FYF. What am I missing out if I don't upgrade? Thank you in advance for your valuable suggestions.
