Well. I am new here but have worked in magnolia for quite some time. I only lurk on these forums.
I figured why not give a mild opinion given no one on here is able to fully assist you with you needs.
First off. Wide viewing angles and deeper contrasts are what you are wanting. VA panels in general will be best for your room and lighting situation. I personally am a huge lean towards Sony TVs because they are a mixture of IPS and VA panels. However, given the x950g would be the better option given it has the x1 ultimate processor capable of enhancing even the smallest details adding brightness, contrast and natural color where needed most. This will help with giving most realistic picture quality in conjunction with dolby vision effects.
Now samsung Q80 is a decent TV, samsung is the Q90 or nothing. Reasoning being the more LED “quadrants” that the panel possesses on top of having the highest bit of color in the 2019 TV line up. 4x that of Sony. However, i am not a huge fan of Samsung using their blue hue of LED lighting to capture the “wider spectrum of color they claim”.
With any TV calibration is ideal, and highly recommended.
Back to Sony, I do like the Netflix calibration mode it offers if you are a streamer. Quite interesting. The Sony TV’s quality in their flagships mimic their superiority in the movie production industry, noted the x950 wouldn’t be equivalent to the oleds black and white levels, it still is an awesome panel when comparing to the samsung. When we have had the samsung/sony side by side, without calibration, out of the box, Sony has less peak brightness, but crisper lines and more clarity with picture. When panning in a motion picture such as “pirates of the Caribbean” there was motion jitter with the samsung, flawless with the sony. Blues and purples were more vibrant with the samsung, however greens/browns/reds were realistically apparent with Sony.
Samsung is more for gaming.
