Ratios exist for a reason

Gradients and photography
Automated tools sample pixels; busy backgrounds create false passes or failures. Solid scrims behind text usually help both readability and measurement stability.
State styles
Hover, focus, and disabled styles need their own contrast checks. A beautiful default button can become illegible when dimmed.
