por que o mediainfo não fornece metadados de uma imagem como o exiftool?

Já faz um bom tempo que estou coçando a cabeça com isso. Vamos ver o que o mediainfo diz em uma imagem -

Agora vamos ver a mesma imagem no exiftool -

Eu fui para o upstream do mediainfo e vi esta página, mas não consegui compreender em qual recurso votar, então ele fornecerá mais informações de metadados. para imagens.

Também vasculhei a página de manual local, bem como --help, mas não consegui ir muito longe. Eu sei que o mediainfo é mais adequado para arquivos de vídeo e áudio do que para imagens, mas seria bom se uma ferramenta pudesse fazer tudo.

Estou executando o exiftool 10.80-1 e

$ mediainfo --version
MediaInfo Command line, 
MediaInfoLib - v18.03

em testes Debian.
