On my 2018 Mac Mini, I see AppleIntelKBLGraphics (Kaby Lake) and AppleIntelCFLGraphicsFramebuffer (Coffee Lake) extensions loaded.
With macOS 10.14.2 these extensions were both version 12.4.7.1 - with macOS 10.14.3 they are now version 12.4.7.2.
We'll probably never know what changed, just an observation
I was looking for better monitor wake-from-sleep support. Too early to tell.
Curiously, both 12.4.7.1 and 12.4.7.2 have the same Last Modified date of 11/26/18 at 11:31PM - so doesn't bode well for significant changes.
