Oneplus 13 pre-installed screen protector is amazing. How do they do it?

I was put off from screen protectors for many years ever since curved screen phones began to dominate the market. Tempered glass just didn't adhere well and soft TPU felt too rubbery. I tried every type of screen protector there was, and took all of them off within two weeks. However I have been using my oneplus 13 for more than two weeks and I'm still loving the stock screen protector. None of the micro scratches are any deeper than if I had used my phone naked, and the oleophobic coating still feels oleophobic. I can't believe soft screen protector technology has finally reached the level where it actually feels like a screen.

What technologies are used to achieve such properties and how can I find similar screen protectors online?
