To clear things up on SSJ Rosé.
DBS Anime: It is never stated if it is a variant, and due to the improvement it gains, it almost seems like a new super saiyan form entirely. However, a poster related to the anime (secondary canon, I guess?) states it is Gokü Black's version of Super Saiyan.
DBS Manga: It is stated outright to be the divine version of Super Saiyan God Super Saiyan. Due to pink/rosé coloured hair, it is nicknamed SSJ Rosé and not SSJ Blue. It was achieved because Zamas' soul fully merged with the saiyan cells.
Verdict: Due to contradictions between the two, it's hard to say, especially nice we don't know how reliable the anime related poster is. It would be safer to leave it be, but since we use the anime for our source on DBS, and the poster is likely secondary canon to the anime, it could be seen as his version of Super Saiyan. Personally, I'd treat it as its own thing just to be on the safe side though.
