that was my thought as well ("yay marketing") but apparently it's actually structurally different so that it maintains contrast. I ordered one in early march and if it ever actually arrives I'll try to remember to reply on visible difference :D (not kidding, it was due late march, then slipped to Aripl 22-27, and today moved to May 23-?? )
I have the nano textured XDR Pro and chose to order the Studio Display without it. Iām a data point of 1 obviously, but it diffuses the image quite a bit in my opinion.
