Probably, but this is a rabbit hole all in itself. All aspects of life are dictated by others' perception of us, our work and our personality being signals just as appearance is.
In an ideal world, we could simply uncheck these biases and do blind promotions and detach a person's work output from his or her face, but it doesn't work like that. Even worse attractiveness is subjective and thus hard to control for. You can usually identify racism because the person will have traits that puts him/her in that category. It's much harder for subjective beauty.
TLDR: Probably yes, but don't expect it to go away anytime soon.
