As a photographer using a light meter you need to look at the skin. Taking a reading will give you exposure that would render the color neutral gray. Then you have to make adjustments to make it lighter or darker depending on their True Tone.
The picture is fine. It’s exposed properly. People making judgements are doing so on uncalibrated monitors hat should be “brighter.”
Politically, I don’t care for Annie. But as a photographer, she is probably the best portrait shooter in history. She doesn’t make exposure mistakes.
They are only saying it because she’s white, period.
