Sorry, but no. A square is just as real as a circle. You are just playing semantics, really.
And I would like to see you sit down and actually come up with a logical configuration of a pixel matrix for a circular screen and then visualise how that would actually be better at displaying lines or anything really than squares at high DPI counts can. If you would have the same DPI with round vs square pixels i posit that the round screen would have a lot more wobbly looking image, unless you just put the round pixels in a square grid, in which case you would have a darker image with otherwise the same result.
I suggest you actually sit down a bit and think your ideas through instead of just blurting them out once you get them.
At least that is the impression you are making. You made 94 videos since the 23rd of may. That is over 2 videos a day on average. And it does not look like you are getting much if any real feedback on them. If this is somehow a substitute for real human interaction for you then I would suggest to find some friends IRL and hang out with them. Just a suggestion.
