Black and white images seem to have more leeway in their acceptability. We don’t judge them the same way as we do colour ones. Adjusting tones in colour landscapes comes with a caveat. Different if your doing cityscapes or some variety of indoor shoots like music concerts. Noone judges them much from colour point of view because of the coloured lighting that’s standard for such an event. Colour landscapes can’t stray too much from the established standards provided by stock films of the analog era and more recently film simulations from the likes of Fuji. But using Nostalgic Neg simulations on a rainforest scene would not seem appropriate. Silver Efex on the other hand in the version I use at least has 58 different conversion options for B&W. Granted, some of those are also not suitable for the most part - like Film Noir or Antique. But there’s still a lot of latitude which then comes down to taste.
