Case closed, I added the user to video and render groups.
Now the GPUs that should be visible through the legacy OpenCL are visible.

sudo usermod -a -G video $LOGNAME
sudo usermod -a -G render $LOGNAME

I find it interesting that you're using a Vega 10 GPU with 'legacy' OpenCL. I thought Vega onwards needed PAL or ROCr-based OpenCL to function under recent amdgpu-pro drivers. Are you running the Vega 10 GPU successfully with 'legacy' OpenCL?
