Photos I took on Sabbath during the worship service. The Georgia Dome is the home of the Atlanta Falcons, a football team. I bring this up because it will help you understand the shape of the building. The floor is the playing field and the seats surrounding it are the bleachers. IOW, it is oblong. The first picture is toward the stage which is at one end of the the field where a goalpost would be.
This view is opposite the stage
Finally, this picture is more to the middle but still shows some of the stage. On Friday, only part of the lowest tier of seats was filled. On Sabbath almost all of the first two tiers was filled with a few on the third tier. Between tiers 2 and 3 are the private boxes on two levels and the press box. There were people there too.
You can see that there are a number of video screens. Without them, you wouldn't be able to see much on the stage unless you are right in front of it.
