Problem with custom theme (JSON)
You are correct - JSON themes do not overwrite custom formatting options. You'll have Revert everything to default formatting if you want it to use the themes: https://docs.microsoft.com/en-us/power-bi/create-reports/desktop-report-themes#situations-when-report-theme-colors-wont-stick-to-your-reports
Good news is, you can use the Format Painter to copy formatting for many visuals (especially those of the same type).
