Does Unit use python interpreter from venv if venv is already activated?

[bunny-therapist]

The docs for python applications say

The Python version used to run the app is determined by type; for performance, Unit doesn’t use the command-line interpreter from the virtual environment.

However, if I have already activated a virtual environment (which sets VIRTUAL_ENV and modifies PATH), and then run unit with unitd from the command line, will unit figure out that a virtual environment is active so that it can ignore it, or will unit just find python via PATH and thus use virtual environment's interpreter, despite what the docs say?

I am asking since, based on the docs, that would mean decreased performance (I don't quite understand why, but ok), so that I would have to make sure that no virtual environment is active when unit is launched.
