Considering picking up an LG UltraFine 5K display to use with my new 15" tMBP. While I know the convenience of just having one cable is great, and something I'd lose if I went with another display, how does the quality of the actual panel in this compare to other displays? Color rendition, uniformity, ease of calibration, etc. I'd be using it mainly for photos and text documents so while the 5k is great, I don't necessarily need it, and could run with two lower resolution monitors if this one isn't really worth it. Any feedback is greatly appreciated. Thanks!
