 Yes, I discovered the existence of `OpenCV3` and its `py-opencv3` binding
 when I updated

 {{{
 opencv @3.4.14_0+python38 => opencv @3.4.14_0+python39
 }}}

 This prompted me to install `OpenCV3` to a try to substitute it for
 `opencv`.
 I then tried to install `py39-opencv3`.
 The failure suggested a conflict... prompting me to uninstall `opencv
 @3.4.14_0+python39` which I then reinstalled due to the persistent failure
 of the `py39-opencv3` installation.
 Moreover, I use `pyautogui` which in turn uses `OpenCV` itself but I don't
 know at this time if it uses or can use `OpenCV3/OpenCV4`.
 Here is the current status of `OpenCV` & `OpenCV3` on my machine:

 {{{
 opencv @3.4.14_0+python39 (active)
 opencv3 @3.4.14_0 (active)

 }}}

 What can you suggest more to me?
