@kkempter-getswift could you please follow the guideline outlined on the RPU,
i.e. please provide all the nessesary samples (i.e. all 4?, including re-shooing existing samples)
from said camera of the same scene, ideally something like daylight landscape?

Looks good to me for both 3FR and FFF w/ the new samples, thanks @kkempter-getswift
