[W10 1803+] Broken ColorizationColor transparency value...

So uh, I've noticed that Windows 10 (1607 and later) broke the ColorizationColor values in both the Control Panel, and the UWP Settings app. Since Windows Vista, there has been a registry key that's responsible for the colorization color of the caption bar and border of windows. It's a 32-bit hex value and its format is ARGB (Alpha, Red, Green, Blue), so for instance, a value of 5d6e110b would have "5d" as its alpha value, "6e" as red, "11" as green, and "0b" as blue.

So, the current ColorizationColor value is stored at Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM.
Theme files (.theme) also use that value in their files to set that registry value to the corresponding value whenever you apply the theme, except it's actually broken:

For instance, instead of setting the colour to "528D5A94" (because the theme file has this value inside), the registry value gets updated to "C48D5A94" instead, which causes it to have a different transparency value.
Not only are themes broken in both the Control Panel and the Settings app, but changing your colour via both of these 2 also gets you broken transparency values (being set to "C4" every time).

Even the color intensity slider in the control panel is broken and doesn't change anything visually and whatever value you set it to gets reset to about 77% (which is C4 in hex) whenever you come back to this page... FYI, the slider is supposed to change that very transparency value from the ColorizationColor value I've been talking about, like it used to before Windows 10, and it should have at least given me a gray colour like in Windows 8.X due to Windows 8.X and 10 not having Aero Glass out of the box... (I'm using a Windows 7 visual style, uDWM.dll patch that makes the caption colors work the same as in Win7, and Glass8 by BigMuscle in the screenshot below on my Windows LTSC 2019 (1809) setup)


Now, that's a problem for me, because I just got the idea of trying to make a program or bat file that makes Big Muscle's Aero8 transparency and StartIsBack++'s transparency values sync together whenever I try changing my color like it used to in Windows Vista, 7 and probably 8.X (on the taskbar) (Windows 8.X's taskbar stays at the same transparency no matter what, however, it didn't have the broken ColorizationColor and has its colors gray when the color intensity is set to 0%) as well.

I hope it's not another issue caused by 7TSP confounding 32-bit and 64-bit versions of system programs... (It doesn't seem to be the case as it still occurs on vanilla LTSC 2019 after testing a week later in a VM)

02/29/2024 EDIT: 1607 seems to have added the AccentColor value, which does break ColorizationColor. This is bad, because it would only work with 1507 and 1511...
