The recently launched Huawei Y9 Prime (2019) is receiving the EMUI 9.1 update.
This update brings in GPU Turbo 3.0 to the mid-ranger in addition to improved performance and new wallpapers and icons. Perhaps the biggest performance gains come because the firmware switches the file system of the Y9 Prime (2019) to EROFS which Huawei says can increase the random read speed by 20%.
The EMUI 9.1 update is currently seeding in India but it will be rolled out in other markets as well. An exact timeframe of the rollout is currently unavailable, though.
