Why doesn't the iFixit iPhone 5SE Display have IPS screen technology?

According to the specs for the iPhone 5SE, the original LCD screen comes with an IPS Display: (https://www.pdevice.com/product/apple-ip...)

This basically means that when someone looks at the screen at sharp angles, the quality does not degrade or appear darker/lighter than the original image.

Without IPS, someone will only see a good quality image while facing the screen head on. If they look at the screen from a sharper angle, then the viewing quality degrades.

This makes it difficult for 3 people to watch a video when they’re all seated next to each other. The person in the center will get a good view, but the other two on the left and right side will see lower color gamuts and quality in the display.

Here is a good example, with IPS Displays on the left side and standard screens without it on the right:

After I replaced by iPhone 5SE Screen with the one from iFixit, I noticed this disadvantage almost immediately, but didn’t have the know-how to figure out the problem. After researching it, I realized that this problem with the video quality is because iFixit’s screens DO NOT have IPS screen technology. Why is that? IPS Technology isn’t solely owned by Apple, so I don’t understand why it wasn’t implemented in these iFixit screens.

I’m definitely disappointed with this realization. If my old iPhone screen wasn’t so beaten up then I wouldn’t have replaced it if this is all iFixit has to offer.
