From what I understand they still seem to render at 1080p and then upsample to 4k. Judging by Soul.

That seems extremely unlikely. The Renderman software they use has no issues rendering at 4k.

It's not really that unlikely. Most films render at 2k DCI. It's not so much that the software and hardware can't render higher, it's just diminishing gains for the increased render time.

Most 4k films till very recently actually have the digital elements at 2k DCI-ish resolutions and are upscaled. I can't speak to wether soul is rendered at 2k or 4k, but it wouldn't be surprising if it was 2k upscaled.

That's more accurate, Soul was probably rendered at 2k, as most of their movies.

If a shot doesn't look good enough when upscaled, they re-render in 4k.

Actually, they used to upscale most of the movies using Nuke, but recently, started using deep learning for that. At Siggraph 2020, they gave a talk on this topic: https://s2020.siggraph.org/presentation/?id=gensub_443&sess=...
