In theory, the Netflix app on a smart TV could use the whole image processing and optimization machinary and magic (such as interpolating frames) offered by that specific smart TV, but it's very doubtful if it does such. But since you're not planning to use such an app, that should not be a factor.
But maybe the Netflix app on your Windows 10 PC will be smart enough to adapt its controls to the video card in your PC.
Also, you might notice that the TV (depending on the model) has more options to finetune its settings. After all, we do have a http://forums.cnet.com/hdtv-picture-settings-forum/?tag=contentMain;contentBody here, but not a forum for monitor settings, and that shoud have a reason. Also it might depend on the type of connection between your PC and the TV: that could be something wireless, DVI, hdmi or (depending on you video card) composite or component.
So it's difficult to say this in general. If I were you, I'd find a laptop to view Netflix on and compare different monitors and TV's in the shop to see what you like most. It's an interesting experiment so you might be able to find a sales person that is interested in the outcome.

Do HDTVs have better picture quality for displaying movies/videos? Main purpose of my PC is to play movies (such as Netflix), and I'm trying to decide whether to go with a 24" monitor or 24" HDTV?
