I think the differences will be stark and obvious to those who remember the world pre-convergence. But a new generation will not know the differences, nor will they care. For my parents' generation, TVs were a big deal. For me, I can hardly distinguish between a TV and a Radio and a Microwave and a Washer/Dryer -- they all have existed as long as I remember. But I can definitely tell the difference between an app written against User32/GDI/WinForms/VB versus one that uses the Android toolkit versus one in GTK+. There's been a lot of work over the years to make most applications agnostic to the underlying toolkit and OS, including React Native, Flutter, Unity, Adobe Animate (formerly Macromedia Flash), and so forth.
