btrfs-progs v4.17.1 man btrfs-scrub:
-R
print raw statistics per-device instead of a summary
However, on a two device Btrfs volume, -R does not show per device
statistics. See screenshot:

Additionally, the description of -d and -R doesn't help me distinquish
between the two. -R says "instead of a summary" so that suggests -d
will summarize but isn't explicitly stated.
