I'm looking at the Samsung UN55MU6500FXZA and UN65MU6500FXZA . I'm really indecisive here, in my pictures I have the 55" setup but I'm debating if a 65 inch would look better and look more appropriate in that space. Thoughts? Budget really isn't a big concern, I'd more or less just want the best experience and what looks best with my setup.
Thank you!

Bigger is usually better but it does depend on how far from the screen you sit. Try making a mockup of a 65 with some cardboard to give you an idea of how the bigger set will look.

What is the ideal distance for a 65 inch 4k tv?

I tried to capture the distance between the couch and TV stand in my photos.
