Definitely not global (probably NP hard) but it’s likely optimized in some basic sense would be my guess. (Probably still using very specific parametrizations of the lenses and such.) At some point we’ll just use metaoptics for lenses that are fully optimized using some general heuristics, but so far I am not sure they (both lenses and heuristics) are ready for prime time :)
