You are likely to be unable to source the missing IPv4 traffic over IPv6.
I’m not familiar with JIO’s setup, but that’s an interesting question. If their IPv6 was down, would their network still be able to deliver? Would they run out of CGNAT capacity or IPv4 translations?

If their IPv6 failed, they would almost certainly run with significant service disruption.
IPv6 is no longer optional for them. I suspect it's not optional for T-Mobile USA either. Or Facebook/Google/Netflix.
Surely you need enough IPv6 capacity incase your IPv4 transit fails as well. If JIO could have built enough IPv4 capacity to run their network over IPv4, they would have, but they can't, so they've been pushing IPv6 hard.
