the 1st few gen of foldable highlighted the big internal screen. it is full screen for apps and games or split screen use.

but for video content, i put side by side z fold 4 internal screen and s23 ultra in landscape mode, the video size is the same. internal screen can fullscreen but its cropped.

i think to truly be tablet replacement, they need to innovate still. thinking of the consumer level tri-fold design now still in prototype stage
