Carrier Aggregation on Airtel 4G LTE

Jio Pings are very bad nowadays especially for Pubg used to get 40-100ms earlier but nowadays it's 120-200ms. Whereas in Airtel 4G i get 20-80ms. Jio Pings are similar in both 4G and Fiber.

Here also ping on jio fiber goes upto 80 to 100ms where as bsnl fiber is able to maintain 20 to 25ms.
Airtel Fiber is not available here yet.
 
There is some issue in carrier aggregation with jio. Band 40-40 CA with 10Mhz as primary band gives 30-40Mbps but with 20Mhz as primary band getting 80Mbps. It should be same in both right ?
 
Intraband CA is useless. For me Single Band 40 on Nokia and Intraband CA on Galaxy A70 gives similar speeds. Speeds increases only when it latches to either Band 3 or Band 5. Even when I'm very close to tower I don't even get full 100Mbps on Intraband CA.
