My coworker was able to fix the problem by giving the .pptx file to AI so it manually edited the theme. It reported that the reason for reverting was that #93D2FF was stored in two separate places in the template rather than just one:

I'm not sure if the explanation rings true, but this permanently fixed the color code to the correct HEX/RGB values without issue.
