Whitelist is intended for other use. It tells Kodi that it should passthrogh all listed video resolutions directly to output, without doing anythig to them; similar to audio passthrough for chosen audio formats.
If you want Kodi to do something to a certain resolution, then you don’t put that resolution into the whitelist.
The whitelist works only for files that ecsactly match resolution and frame rate that are listed in it.
