Pro-mode in camera has banding and blotching: anyone else? fixes?

[AC Question]

As per the title, I've been seeing color-bands and color-blotches in my pictures when I use Pro Mode. Not sure if this is related to problems shooting while under LED lights. Have tried altering the white balance but to no avail. This doesn't occur in Auto camera mode. My friendly local phone store guy said he's seen this in auto mode on his S6, S6 Edge and S7. Anybody else? any fixes?
