Both 'mkdtimg' tool and the 'mkdtboimg.py' script seem to lack the capability of extracting the original dtb/dtbo blobs from the dtb{o}.img file.

jFTR, below 'dd' workaround comes to the rescue.
$ dd skip="dt_table_entry[i]->dt_offset" \ count="dt_table_entry[i]->dt_size" \ if=dtb.img of=i.dtb bs=1
Just checked in AOSP/master, seems like the feature is there, it's called "dump".
$ mkdtimg dump dtbo.img --dtb filename
For details see:
$ mkdtimg help dump
mkdtimg dump <image_file> (<option>...)
options: -o, --output <filename> Output file name. Default is output to stdout. -b, --dtb <filename> Dump dtb/dtbo files from image. Will output to <filename>.0, <filename>.1, etc.
You can convert dtb to dts further, using "dtc" tool.
Many thanks, Eugeniu.
