Summary

uv pip list and pip list's outputs seem to refer to package names differently. I believe uv is using distribution package names, whereas pip is using import package names.

uv init uv-pip-list
cd uv-pip-list
uv add docstring-parser jaraco-classes pymupdfb pypdf2 pip
diff --side-by-side  <(uv run pip list) <(uv pip list)

Package          Version					Package          Version
---------------- -------					---------------- -------
docstring_parser 0.16					      |	docstring-parser 0.16
jaraco.classes   3.4.0					      |	jaraco-classes   3.4.0
more-itertools   10.7.0						more-itertools   10.7.0
pip              25.1						pip              25.1
PyMuPDFb         1.24.10				      |	pymupdfb         1.24.10
PyPDF2           3.0.1					      |	pypdf2           3.0.1

Notice that the _ in docstring_parser (pip) becomes - in docstring-parser (uv), case in PyMuPDFb is lost, etc.

Not sure this is a big deal. When I switched a system over to uv, it broke some old code that parses the output of pip list. Honestly, I might prefer uv's choice, since it matches with what you'd uv pip uninstall/install. But given how widely pip list is probably parsed, being consistent might be preferable.
