NVIDIA blob driver

First, let me state that I know very little about graphics cards/drivers. I have almost always used the the Nvidia "open source" drivers. I decided to change over to the proprietary driver since I saw that the SBo version is 440.44 and I want to mess around a bit with the cuda capability. I have a GTX970 card. I dropped down to non-graphics mode, ran the xxxxx.run --uninstall to remove the existing driver then built and installed the nvidia-kernel and nvidia-driver packages. Startx started up the plasma5 environment just like normal. Looking in the /var/log/nvidia-installer.log I see -

Code:cat nvidia-installer.log

1) How can I tell unequivocally if the blob driver is installed?

2) How to resolve the two warnings in the installer log about nvidia-uvm and nvidia-drm modules not being installed.

I have done a lot of searching for answers but so far it is as clear as mud. Any help will be appreciated. Thanks in advance.
