The major thing you have to look out for it Chroma Subsampling[https://en.wikipedia.org/wiki/Chroma_subsampling] - basically many TVs use a lossy colour compression to pack higher resolutions/refreshrates over the same cable. It's not normally noticeable during content like movies, but if you have a lot of fine details (i.e. text) it can cause noticeable colour fringing.
Some TVs (mostly OLEDS) also have unusual sub-pixel layouts, and this reportedly can cause issues with various subpixel rendering schemes for text (once again manifesting as colour fringing). OLEDs also have various measure to counter burn-in that may be annoying on a monitor, like dropping the brightness after a few minutes of innactivity, or shifting the whole image by a few pixels now and again.
On the CU7000D I pulled three wires and I was able to turn off Bluetooth on the fucking thing.
For those about to make the recommendation, I could not make the edit in the factory menu. I use the remote controller code, but Samsung neutered their factory menu options unless the person has full-fledged factory remote.
