The 6th wire is behind the lower neutral, look closer. I would have went straight up and moved the POA.Looks like 5 wires coming out of the weatherhead? Parallel hots and derated neutral? The panels left and right of the meter will pass inspection here, but the POCO won't touch it.
How big of a hammer did they have to use to get those wires in that LB?
And why would you spend all that time rather than running straight up? Maybe there is a goofy requirement for all attachments to be on the backside?
