We have released 3×3 video for all of the Government clouds, on desktop and mobile.
We will soon bring Large Gallery view to Microsoft Teams, providing a new way to view video up to 49 participants at once on a single screen (7×7).

You should add that the 3x3 feature is still not available for the Linux Desktop application, nor has Microsoft provided an ETA for this.
