Spyder5 Express with Windows 10 issue

[8bit]

I asked this over on Talk Photography earlier but thought it might be worth asking here too so here goes...

I got a Spyder5 Express monitor calibration tool at Christmas time. The computer is Windows 10 64-bit with the latest updates including the Fall Creators Update. The first time I ran the calibration there was no visible change on the screen at all.

I had a look on the Datacolor website and found a knowledge base article saying this is a known issue with Win10 and that Creators Update:

I did as it said, removed the driver and calibration software, removed all the other stuff, reinstalled and did the calibration again. This worked, now the screen colours looked quite different and more natural. Now though, I can't switch between calibrated and uncalibrated profiles, or rather I can but they don't look any different. So I'm not sure if what I'm seeing is the calibrated view (and I've just gotten used to it) or it's gone back to non-calibrated. I don't want to have to remove and reinstall the software again to check.

Datacolor apparently haven't been able to reproduce the issue so there's no fix and I already have the latest version of the software (5.2 for Windows). Has anyone else seen this issue and maybe found anything else that will help, short of going through the whole reinstall process again?
