There is the app Krita Brush Info, this app is able to compare two Krita brushes, even in bundles, and then gives an output on the result of that comparison. But it will also show you the info of a single brush that you inspect with Krita Brush Info.
The app needs another app to extract the data: Exiftool (this link leads to the original commandline version without installer), and this is the version with installer from Oliver Betz.
If you want you can use the version I have uploaded to my cloud, just unzip it to any folder you prefer, Exiftool is already included and installed in the package. Both are the most recent versions.
In the root-folder of that archive, you find the ZIP’s with Krita Brush Info and its sources, as well as the Website copies of Krita Brush Info’s description and from its GitHub repo included. And the installation folder KritaBrushInfo v1-1-0 is also there.
After unzipping, on the first start of Krita Brush Info, you just have to point Krita Brush Info, from the folder KritaBrushInfo v1-1-0 to the ExifTool.exe in the same folder where the Krita Brush Info.exe resides. To set this up, you only need an RMB click anywhere in the Krita Brush Info-window to open the preferences’ dialog where you can enter the path to the ExifTool.exe.
