Hi, I've also uninstalled VMware Tools, and ran the compatibility appraiser using the command I posted earlier. Like you, I received a success message even though it didn't update the result in the Windows 10 reservation app (and I also left it to run like you did).
Unfortunately, this is the only way I found on the internet to update the result of the compatibility check, other then to leave it to do it automatically (my test updated itself automatically two weeks after it was first run but I still had VMware tools installed then).
So, to cut it short, I'm in the same boat as you and have confirmed your results. I need Windows 8.1 to run at native desktop resolution, so will be reinstalling VMware tools, and I hope that VMware can resolve this problem with Microsoft.
Of course, as wila pointed out, Windows 10 will be available to download even without a reservation, but it would be nice to be able to take advantage of this offer.
