"Camera Body No." is the description for the Canon "SerialNumber"
tag. I know this may be a bit confusing, but it is done this way to
match the description used by the Canon software.
The command you used will change the "Camera Body No.", but
since you didn't specify "Canon:SerialNumber" it also added an
XMP SerialNumber tag, which is the only tag you saw in your last
command since you didn't use the -a option. You
may find it helpful to read

number 3.
Also, you can see exactly what is happening if you use the -v3
option when writing the SerialNumber tag.
