The last four digits of the driver version will indicate the driver version, Intel uses the following schema to define the driver versions:
In your case the 20. means that you have Windows® 10 and the rest of digits indicate the DirectX* version and the build number.

That's brilliant. You learn something new every day!
However, I must say that also means my PC somehow has a version (4331) newer than the supposed latest that the Intel Driver Updater and website displays (4320)??
(Also, 40 in the latest version doesn't appear to match a Direct X version either?)
Sorry but I'm still confused. How does the latest driver version match Intel's very own versioning document?...
15 doesn't exist as operating system and 40 doesn't exist as a Direct X version. Not only that, but even if they did, surely they should match the ones I have on my PC already - 20 for Windows 10 and 19 for Dx12?
The Intel Driver Update Utility and the websites "latest" drivers for my NUC are really not helping the end user decide if they actually need this new version when the numbering system is all wrong.
Lastly, the ones with no current version listed, how confident can I be that the "latest version" is indeed newer than the one the utility has failed to display a version number for?
Thanks for you time @amy_intel
The 15. and the 40. are just for Intel reference. Once you install the driver the version will change according to your system.
Could please let us know your NUC model? I would like to check the driver version manually from Drivers & Software.
At the following link Drivers & Software you will be able to find the latest drivers for your NUC, you can compare them with those listed on Intel® Driver Update Utility and install the manually from that link.
