I'm looking to reverse the changes the calibration tool made. Every time I try and delete the calibration and start again, it doesn't seem to erase what it already did and start over. It seems to try and refine what I've already made and it ends up looking worse. If I use reset-all.exe, will that reverse the changes the tool made? What about if I reset Windows?

Also, I am on a laptop with a built-in display. In CRU, I have two monitor profiles. One is active and the other one is not. Is that because I have two GPU's? The one that isn't active has more extension block info. is that for my other GPU or is that the way the monitor was before I used the calibration tool? Also, the second profile has displayID 2.0 info with a section labeled other and another section labelled CTA data blocks. Both are greyed out. Is there a way to see that information?

The HDR Calibration app does not change the EDID. It creates a color profile. Running reset-all.exe removes all EDID overrides and resets certain display settings, but not color profiles. The color profiles are listed in the Color Management control panel. After removing the profile, the colors should reset after restarting Windows.

Inactive display entries are usually from the basic display driver that is used before the driver was installed or while running restart.exe, or it could be a leftover from an older driver. CRU currently can only read detailed resolutions and tiled display topology from DisplayID extension blocks.
