I'm not sure if the anime will ever get there, but if you read the manga past the end of Super (which ends on the Tournament of Destruction saga last I checked, like the one with Jiren, and then the Brolly movie), there's more Frieza development. Btw I suggest reading even the parts at the start; it's more of a companion piece than the retelling of the exact same story on a different medium. There is overlap between them, of course, but also a bunch of not overlap. Like Zamasu is more fleshed out and his whole path makes more sense in the manga.

Anime has more fighting, manga has more story telling.

Oh jeez, so like... In super or something. That's amazing. Does Lunch ever come back after z? They just did her so dirty...
