Female sexual arousal is more complicated than male attraction.

Her first impression is physical/visual, like male attraction. The commonly cited psych and Tinder studies focus on that isolated first impression of a photo, so only the physical attraction component kicks in. Porn has a similar effect. When it comes to photos, they're just as visual as men (although the visual cues aren't just physical features but also style, mood, presence, etc.).

When women interact with men IRL for prolonged periods of time, emotional bonding kicks in and her hormones distort how attractive his features look to her brain. She can get obsessed with his face or some other feature, even if it's objectively average looking and there are hotter men hitting on her. That's because she's not a computer performing an objective analysis of his features. Her arousal is based on how she feels around him, and her emotions and hormones change how she feels and how she perceives his looks and sexual attractiveness.

Looks still matter but they're not all there is to sexual attraction for women.
