I have eye strain using iPhone 14 pro

Probably not pwm, but temporal dithering. Check ledstrain.org

Apple and others compete on "most colorful" screen and probably do some tricks with software to make the eye believe there are billion of colors....a lot of people have similar symptoms, mainly headaches...

There are a lot of complaints regarding headache and nausea feeling for all phones which are produced since two years. It probably has something to do that phone brands are competig on the best screen, and have some sort of trick done in the connection between the graphic cards and the screen (colors). I tested 15 phones and the Apple 14 gives me the less headache.

I have visited Apple Store twice to get the issue resolved but it hasn’t worked.

Unless they have started hiring ophthalmologists at Apple Stores, it's unlikely that they will be able to resolve anything.
