`uv pip check` gives a different result to `pip check`

[strickvl]

Added uv pip check to replace pip check in our CI (i.e. here. The CI passed previously without issue when running pip check, but when switching to uv I get the following error:

Run uv pip check
Checked 81 packages in 0.71ms
Found 1 incompatibility
The package `pip` has multiple installed distributions:
  - /opt/hostedtoolcache/Python/3.8.18/x64/lib/python3.8/site-packages/pip-23.0.1.dist-info
  - /opt/hostedtoolcache/Python/3.8.18/x64/lib/python3.8/site-packages/pip-24.0.dist-info
Error: Process completed with exit code 1.

Is there any guidance / docs on how uv's pip check differs from normal pip check?
