I have a 100Hz TV and the top end model of that range interpolates the "missing frames" to smooth out action.

Upscaling is simply the changing from one resolution to another, pixel doubling is by definition upscaling.
You will get the same amount of jaggies using pixel doubling from HD to UHD as you would viewing the HD content on a native panel of the same size.
Whilst you can use more advanced techniques to attempt to improve the picture my point still stands, the absolute worst case on viewing HD content on a UHD panel is that you get the exact same picture as you would have on a HD panel of the same size.
This is entirely different than viewing SD content on HD (or SD on UHD) as there is always the need to interpolate pixels when upscaling there.
There are no "missing frames" with upscaling. You 100HZ tv interpolates missing frames because of the difference between the refresh rate of the panel and the frame rate of the signal. It has nothing to do with upscaling at all, they're both entirely different concepts.
