No, what you’re seeing is the project without a storyboard. When you modify the plist to use NSMainStoryboardFile instead of UILaunchStoryboardName then the setting is ignored because, as the name suggests, NSMainStoryboardFile only applies to macOS apps. As there is no storyboard being used the app resolution is much smaller and is no longer fullscreen so it might look like it’s using the safe area that you defined, but it isn’t. If you want to use a custom storyboard with a different safe area other than fullscreen then you will need to create your own .storyboard file, and add the path to it to the “Custom Launch Storyboard” setting in the iOS exporter (see this post for more info).
