    If `score_name` is provided, we just return it as-is.
    If `score_name` is `None`, we use `Score` if `negate_score` is `False` and
    `Negative score` otherwise.
    If `score_name` is a string or a callable, we infer the name. We replace `_` by
    spaces and capitalize the first letter. We remove `neg_` and replace it by
    `"Negative"` if `negate_score` is `False` or just remove it otherwise.

    A value larger than 5 typically indicates that the parameter range would
    better be displayed with a log scale while a linear scale would be more
