It is a weird setting. Changing it outside of the colorscheme triggers setting colorscheme to default. Changing it before defining Normal highlighting group in colorscheme is useless because defining Normal group triggers calculating this setting. So I think you need to check it in the colorscheme (at the top), save there and set it again after defining Normal group (because automatic detection is constantly false, especially on 256 color terminals). You cannot protect your colorscheme from the user that set this option *after* loading the colorscheme, so just mention this fact in documentation.
