This is a tangent, but I’ve been wondering… and perhaps HNera know?
I use some basic libre cad programs to plan my dream house project. And their renderings are pretty non-photorealistic.
Are there any upscalers that can take an inside or outside house render and make it look like something from Pinterest? Meaning the input is an image, not text?
ControlNet maybe? https://github.com/lllyasviel/ControlNet

Play around with the different models, you might get better results with some vs others.
