I hope you mean https://pypi.org/project/opencv-python/ because anything listed on conda tends to be unmaintained junk.
that package lacks CUDA, because that’s notoriously fussy about its environment, and it can’t come with non-free algorithms due to licensing.
if you redistribute a binary package, you’ll be subject to the legal stuff too. I doubt that you’ll need any of those non-free algorithms.
the DNN module has many possible backends. OpenCL tends to work anywhere.
practically, there are no limitations to you and your use case.
