The latent space of type design choices is large but very much finite, and concepts like "warmth" consistently refer to features like large curves, low stroke contrast, deliberate imperfections (that evoke physical reproduction) etc. I'm very confident that this would hold up to a randomized trial.
In this case, "warmth" refers mostly to the rounded corners and unique design quirks, which are meant to imply "I was crafted in analog by a seasoned master draftsman, not merely constructed from sterile geometric shapes by some hipster on a Macbook."
