I just (re)visitied Elevate & Elements. Unlike the other common themes, both do distinguish unsealed from sealed surfaces, but not to the same extent as Desert V4. In my previous screen capture I forgot to mention I have modified Desert to change original yellow/ gray dashes to yellow/ red dashes, so not a entirely fair comparison to OpenAndro themes. Given many common themes have a specific Cycling setting, or even Locus Cycling theme, I don't understand why they don't attempt to distinguish unsealed ways.
