how big a virtual studio can be? stadium size?

we all know unreal engine virtual studios getting more and more popular with tv series and movies.

I wonder theoretically how big these studios can be? at the moment al the studios I know are relatively small or medium-size.

all of this oled or led panels can emit light so this panels have light limitation. that means this studios have some size limitation aswell or is it?

can we make like as big as a stadium size virtual studio with oled or led panels? can that work ?

You also need to take into consideration the range of the tracking system used to track the camera, actors, props, etc… its not just the light panels.

yeah you are right I was only thinking the limits with lights and colors.
