How does display bit-depth affect perceived contrast resolution?

Increasing display bit-depth means there are more gray levels between black and white. With more distinct luminance steps available, the eye can detect smaller differences in brightness, so subtle contrasts become perceivable. This directly enhances contrast resolution, the ability to distinguish nearby brightness levels in an image. Bit-depth mainly affects how many shades of gray can be shown, not how many pixels there are (spatial resolution) or the intensity of colors themselves, so it doesn’t increase spatial detail or just change saturation. That’s why the statement about more gray levels improving the ability to distinguish subtle contrasts is the best explanation.
