If you zoom in YT, you're losing video no matter what considering the phone is not 16:9, notch or no notch. Furthermore the rounded fake corners on that second image are quite ugly.
Agreed, it's a simple concept that was actually for use as a background wallpaper, they expanded beyond the notch as well to further detract from the attention to detail put into it, this is a more accurate idea:
And yes I know there's a loss of viewable content when you zoom in, I was just clarifying the actions around it which result in losing content from the top, bottom, and left side just to fill the entire screen. Any content that fills the graphical output resolution to the display gets the notch area imposed on no matter what which my opinions will always be that it's a distraction since attempting to utilize the full display is an unfortunate compromise that, while tolerable by many here, is definitely nobodies ideal. IT definitely is what it is for now. I don't see Apple inviting more points of failure with retractable camera mechanisms like others have done so we get what we get by how they implement as close as possible the edge-to-edge goal.
Edit: The main issue I've seen is regarding full screen content displayed in landscape like games and apps. I've heard people in Apple stores over the past while commenting while playing with the phones that they feel like they should be able to see whats there and "why is it hiding a portion of the screen". General consumers aren't tech driven are the base customers for Apple products because it's easy, You turn it on and go. They're also not necessarily early adopters of the latest Apple stuff but eventually will come into it. I just feel like they don't understand it as easily. Providing fill in with artificially introducing borders like the image I posted would have made more sense to them in those scenarios because it would give them a "full" experience. That's something I'm very surprised about with Apple on this product design honestly. I'm curious if this was every a concept idea and if so why they ended up scrapping it. Possibly app scaling, it would make for a very specific aspect ratio. Just in landscape scenarios at least would be a great benefit for all, as having those two ears display a small extra portion of content isn't great right now. Developers (don't know if they have yet or not) could take advantage of still using those spots to display content like number of lives or something but I feel the current setup is underutilized for user experience.
