Does PUBG uses QCI 3 in LTE network?

Hello Experts,
Does PUBG uses QCI 3 in LTE network?
(PlayerUnknown’s Battlegrounds)

It should but it doesn’t.
I think no MNO have implemented QCI3 for games.
This QCI3 is a GBR with tough requirements for network, and MNOs have not implemented it.

We have an implemented case above.
