It looks like 'guix environment' does not handles derivations-as-files.
I don't know if it's a bug in the package or 'guix environment':

$ ls -l /gnu/store/i1139n4ab0fn9v4bwkvqzp6sw3w66mqr-python-waf-1.9.5
-r-xr-xr-x 2 root root 99280 Jan  1  1970 /gnu/store/i1139n4ab0fn9v4bwkvqzp6sw3w66mqr-python-waf-1.9.5

$ ./pre-inst-env guix environment mpv
The following derivation will be built:
   /gnu/store/b5ph69m9z0qgwkf1w1p39r3wyab6x4hi-profile.drv
