The problem/route was first climbed by Kevin in 2009 and hasn't seen more than a handful repeats (Honnold, Caldiero, Oddo, Verhoeven, Traversi) before Nina's. Among these ascents, Jorg Verhoeven's stands out a bit. He only used two crashpads.
Although the hardest climbing on Ambrosia comes relatively low, the moves up high are both powerful and comitting. Whether it's a highball or a solo I leave up to you to decide.
Nina's hardest boulder problem to date is Ray of light, ~8B, in Rocklands, and she is no stranger to highball's either with ascents of Evilution Direct, ~8A (FFA) and Footprints, ~7C+, both on the same boulder as Ambrosia, under her belt.
