Nope...

ffprobe -v 0 -of compact=p=0:nk=1 -sexagesimal -show_entries format=duration
test.mp4 | grep -oP "^[\d:]+"

did not work at all! It returned an empty string (nothing)
whereas this:

ffprobe -v 0 -of compact=p=0:nk=1 -sexagesimal -show_entries format=duration
test.mp4

returned this result:

1:08:00.002000

Seems like your grep construct does not work.
