Models are displayed too large / floating on iOS 17.5

### Description

On iOS 17.5.1 we observe two issues on iOS:

1. Models are displayed too large.
2. It looks like the models are "floating" above the ground.

We did not observe these issues in prior iOS versions.

Both issues can be seen in the following videos:

Note that the closet in the background is exactly 200 cm, like the astronaut is supposed to be.

Tested on multiple iOS devices. On Android everything looks fine. Movie clips are from an iPhone 13.
