This is such a cool idea. Text was the one thing I was concerned about with perhaps color correctness/accuracy/calibration options secondarily, but I'm sure they've got that down.
But hearing that the text looks good is the biggest thing. I may actually consider going down this road.
I did this for a bit with a Q900R, a 65in 8k TV - a upside or downside depending on the time of year and climate is that it uses a lot of power and generates a good amount of heat.
One difference between TV and monitor panels is the blue line peak (450 vs 460 nm); lots of people dismiss it as unimportant matter, but to me the further peak towards green the easier it is on my eyes.
I wish the panel was still in production with more dimming zones and DP input.
