I tried getting Emeralde today but it was denied and LTF Saphhiro is offered. Took the card but doesn't seem any benefit like a premium card.
Try to message this toll free number of ICICI 9215676766 and send this text AST YES and you will get call back from the bank and they can help you with more details if you are eligible for any card.
Note: Saphhiro was chargeable for me in imobile but when they checked I got it LTF
