I think it's just an odd shot... I'm looking at other shots taken from similar angles, and her face is better lit here than it usually is when she does the selfie angle. It's making the area around her eyes look unusually light & the area between her nose & mouth looks smoother (like the lines from her nose to the corners of her mouth aren't as pronounced). Her face is also MUCH more relaxed than it ever is - like she's not smiling very widely, she's not doing big eyes, she's not doing anything silly... it's just a gentle smile and very bright, even lighting, which makes it look... unusual & unnatural XD We're used to her being much more animated, I think.
