If you look at the video, I think it is slightly better. However as you know, the 240 fps refresh is the same framerate as the supposed slow mo mode of the samsung so I don't have the ideal testing gear. I briefly looked the video of it set to 60Hz refresh but it was flickering like usual in an alternating pattern (pixel inversion?). I haven't installed the secondary update, will let you know when I test with that.
Symptoms have improved a lot for me over the 60Hz setting I was using earlier last year. I don't get headaches or migraines, just some moderate eye strain over a last couple of weeks. But then I have been using it not as much. I still feel the internal panel is slightly less straining than the LG although both are huge improvements over the "10 bit" Eizo.
