Regarding the A6300, as I recall, those cameras have a decent dynamic range. By any chance, are you using a light meter? Sekonic has a light meter (478 and 858) that will do cinema as well as conventional photographic light metering. You should be able to accurately gauge the lighting of your projects, and can dial in exactly what you are looking for in terms of pushing the lighting. It may give you more consistent results to film at the desired lighting levels instead of adding in post.
