Was more a case of curiosity how different processing affects this. Once I find time I will take a look at it.

One other question that remains is how ​direct​ light sources fit into all of this? Why does a light-source placed in the middle of the frame, aiming directly towards the sensor cause horizontal + vertical streaks? You see how I underlined ​direct​!?

Here is an example. Albeit I am not sure how it may be flawed, because that flashlight uses a convex output glass/lens.

I am not sure about that yet. One idea though is the one outlined in the second-to-last paragraph in this reply to Ken:
