All the LOG profiles are okay, as long as you correct and grade 100% in MLVApp. When exporting without final color corrections you loose a big part of the bitdepth. This means... yes... you preserved highlights and shadows, but at the cost of midtones. Banding is the result.
Anamorphic footage must always be sharpened after rescaling. Otherwise you'll get stair effects. So you must keep the sharpening slider in MLVApp at 0 for anamorphic footage! If I need some sharpening, I apply it in the H.264 / H.265 final transcoding via FFMPEG before releasing the video.
