Mastering is the process of preparing a finished mixdown to be distributed across all formats. There is also an element of finishing touches that are added to round out the completed mixdown. There are plenty of creative decisions that can come into play with regards to dynamic processing and equalization. These kinds of creative decisions are all genre specific and there are numerous approaches to each within a specific genre.
Most importantly mastering is about your music being heard the way it was meant to be heard across all platforms whether that is streaming or playing back on vinyl.
