There should be none.
Note, however, that /dev/mapper/ may contain non-LVM specials as
well, such as cryptsetup(8) ones.
My guess is that /dev/VG/LV may provide some sort of backwards
compatibility, as LVM may have been implemented before Linux's
“device mapper.” (IIRC, there was an LVM implementation for
HP-UX, bearing some similarity to the one currently in Linux.)
