Isn't this done via the microcode-ctl package building a new initrd to
upgrade the kernel at boot time? You can normally see if the microcode
was loaded successfully in the output of 'dmesg | grep microcode', which
doesn't return results until you install the microcode package.

According to the build logs for linux-firmware, it's mainly wifi and SAS
drivers and was last re-packaged/built on 18 Jan 2018-

My guess is the initrd on the live dvd is different from the initrd on
the installer, so perhaps unpack them and work out what the difference is.
