1st post from new user here.. I’m in the process of selecting a set-top box for my TV (Sony XE900 75’). Currently I’m using the TV’s built-in apps. I’ve tentatively limited my selection to the new Fire TV or the new Roku Streaming Stick Plus. My question is, for the same content (let’s say the identical 4K/HDR movie from Netflix), played via the two different set-top boxes (Amazon vs. Roku), would I get identical picture quality (hue, contrast, clarity, etc.) on my TV? In other words, would the hardware/software differences in Amazon vs. Roku lead to the same content being shown differently on my TV? If yes, which set-top box has superior picture quality, or is another set-top box better yet? And as a corollary, would the same content show better quality played via a set-top box vs. my TV's built-in app? Thank you.
