TN panels are still very popular. On those, elements displayed on screen very easily lose contrast when looking at them at an angle.
Back when ads were actually a different background color on Google, I suspect they A/B tested background colors right up to the point that they disappeared on cheap TN laptops. I experienced this first hand when helping a friend with their laptop 5-10 years ago, and they clicked on an ad by mistake. Turned out that the ad background turned white at normal laptop viewing angles.
