I’m not upset and this is covered in the FAQ but as said I have no idea what to do.
The filters are specific to each screens or not depending on them so unfortunately none of those really solve the issue.
Some filters are even automatic depending on your settings and change with time.
For the title it would means title change when browsing and would be even less visible than the filter color that is more visible. Furthermore default Kodi name when auto detected via zeroconf if Kodi (PC-NAME).
So I know you want to help, but this is a complex issue that was thought a lot over the years, if there was something easy / obvious it would have been done
If people do not see the color and the message in the center of the screen they also would not understand what (filtered) means and what to do next.
