Without addressing the main question, a couple targets of opportunity:

1) A quick balance with -mprofiles=single should kill those unused single 
metadata and system mkfs.btrfs legacies so you don't have to see them in 
fi df.

2) While fi df reports the data total vs. used spread being close enough 
that it's unsurprising a balance -dusage=80 didn't give you anything 
back, the spread on metadata is rather higher, dup, 6.0 gig total, less 
than 1 gig used, so a balance -musage=50 or 80 should return a few gigs, 
4-5 I'd guess, leaving you 1-2 gig metadata total.

Maybe that's part of the missing snapshot overhead?

(The -musage run should kill the unused single profile metadata/system as 
well, but for a different reason, so I made it a different point and used 
-mprofiles=single there to avoid conflating the two.)
