This one didn't have the purple hue, it only downloaded Episode 1, all others failed.

This would never have the purple hue as it's not a Netflix show. Netflix shows and Movies have the Red N on the show thumbnail. They are the only one available in HDR10 or DolbyVision.
DolbyVision is Dolby's proprietary version of HDR so it has nothing to do with audio, only video.
So the fact that some have the purple hue while other don't leads me to believe it is your Netflix settings.
Make sure your settings are set to H265 SDR or H264.

If you are using a Windows machine to play your stuff, check that you have HDR enabled (Win+Alt+B to toggle it on and off) and then you can download the H265 HDR stuff. If you cannot enable HDR because of non-compatible hardware, try playing the HDR stuff in a player that does tone mapping.
AFAIK, there are no players doing tone mapping for DoVi. Only HDR/HDR10.
