yes and no. the usual rule is that you're allowed the "basic installation" of the OS and GPU drivers present on a demoparty computer. the fractal geometry example is a poor one since fractal geometry requires minimal shader code to generate, but if you were to trace a modern windows 4k demo it does probably run at least a few MB (if not tens of MB) of executable code between the shader compiler, the GPU driver upload process, etc.
