I don't see gstreamer requiring opencv here:

 ~ $ emerge --depclean -v -p opencv

Calculating dependencies... done!
  media-libs/opencv-4.12.0-r1 pulled in by:
    kde-plasma/spectacle-6.6.4-r1 requires media-libs/opencv:=, media-
libs/opencv:0/4.12.0=
    media-libs/kquickimageeditor-0.6.1 requires media-libs/
opencv:0/4.12.0=, media-libs/opencv:=

I also checked on a PC with an intel CPU & graphics, also running plasma 
desktop.  Same result.

On the other hand, opencv will bring in gstreamer, if it is emerged with 
USE="gstreamer":

 ~ $ equery u opencv | grep gstreamer
-gstreamer
