Ultimately it doesn’t matter what a daemon looks like, says, or does, or even how intensely it materializes. If your real life shows improvement or otherwise manifests the changes you are looking for, that is all that matters.
The converse is true too. The detailed and vivid appearance of a daemon isn’t of much use if it never manifests any sort of change upon the material plane. The entire point of using daemons is to affect the physical world.
For me personally, I had some early experiences with the Goetia…they looked quite like what I expected them to look like. The experience wasn’t particularly intense. Later on I had deeper experiences where the daemons/djinns were more like energy patterns or signatures (i.e. nothing like the pictures in the Goetia), and those experiences were intense and also manifested greater results.
