Bitrates are a question of disc space and content. The AR doesn't impact how high the bitrate can be, so MV being 4:3 isn't the reason for the higher bitrate, the soundtracks are (and maybe how full the BD-50 whole space is used).

However, the bitrate can be used differently. Lethal Weapon is 1.78, so the bitrate is used for the whole screen, while MV only needs the bitrate to serve the "center" of the screen while the black bars can be set at 0 Mbps. So even if MV had the same bitrate than Lethal Weapon, it could focus on a smaller part of the screen.

But no, the AR doesn't push the bitrates higher. I guess that Warner might have not used 100% of the BD-50 whole disc space, or maybe the 12.22 Mbps is the AVB for the 1st disc (which has technically 7 episodes instead of 6) and that the 2 other discs have actually a slightly higher bitrate.
