Cool Effect. No way to solve the swipe up blur - without custom code. Remember this is an APP (To get the same native mobile look you need a lot of custom code).
Regular swipe Slider - you can use webflow Slider - or slider with more options like: Slick / Swiper / Owl / flickity (Search in the forum a lot of slick examples/Q)
Also the heading change + dots animation is custom code.
