I have tested this and it looks as if the "Color and Border" settings set under Tool Properties->Database are not applied to the corresponding database connections after import. The settings themselves are imported though, so that when a new connection of the corresponding type is created, it will get the chosen color and border settings. Also, any color and border choices made in the connection are preserved.

Using version 23.2.4, I exported the settings from one Mac machine and imported the settings to a different Mac machine using the same DBVis version.
Everything seems to import fine except for the tab colors and borders.
I did restart the app several times.
I had everything checked when I exported and imported.
