Why does the screen button execute immediately in dimming mode with backlight off on Galaxy Watch 7 and Watch Ultra?

Before the Galaxy Watch7 and earlier models like the Galaxy Watch6 series, you had to turn on the backlight and touch the screen to interact with it. However, with the Galaxy Watch7 and newer models, the way it works has been changed: now, you can simply touch any button on the screen in dim mode to activate it instantly. This applies across all watch faces, menus, tiles, and other features, and it's the standard way the device operates.
