I'd want to see some actual hard evidence before I believed that. The usual way social cues work is they are devastatingly effective even if people claim they are not. Much like how most interviewers are honestly convinced that their approach is unbiased but in practice they tend to hire people who are like themselves.
My expectation is that turning up in a suit would get better results. The effect is probably smaller in hard-skill roles but I'd assume still present.
