I tested
I deleted supercam from folder / data / data / th_dtv
but when DTV is turned on, the supercam is in this folder again.
I wonder where it gets it from, maybe as you would know, maybe you could change its version.

I think I found the reason why the supercam was reinstalling after its removal when DTV started.
There is th_dtv.apk in / system / app / th_dtv, and that's what causes it.
As it is stored in the system, it cannot be deleted or replaced.
