Pixel 8a launched two years after the current SE, which used an already two years old display: no surprise the screen is better on Google product.Even the Pixel 8a's rather pedestrian display is better in every way than the current iPhone SE's display. If you don't agree, I guess fine - but there's no way to justify that position with objective measurements.
But if you compare it with an iPhone 14 or 15 screen, they are better even if the refresh rate is limited to 60 Hz.
