You should be able to see the blob form models – perhaps there's some error when it runs on your system. It relies on floating-point textures which aren't supported everywhere
Yes with s=1?d=-4 the models are completely clear. I assume the semitransparent glittery look is intentional artistic choice."weird blob" weren't my words but I can imagine how someone could describe it that way considering that half of the time you see the transition animation during which it's much harder to recognize the object.
If you view this link https://lumalabs.ai/genie?s=1&d=-4, do you see the models more clearly?
If you _don't_ I'd be curious if any errors are reported in console
