I've never used a curved 4k monitor (or even seen one), but I use a 32" ASUS PQ321Q at its native resolution for coding. I love it and can't go back. It's right at the edge of what I can discern - any higher PPI and things might look sharper, but I couldn't get any more usable space out of it - I'd have to scale it. It fills my field of view so I I can use the entire screen without having to move my head much, if at all. While I'd not recommend my specific monitor anymore due to non-competitive pricing, I wholeheartedly recommend DisplayPort, 32", 4k, IGZO or IPS monitors for coding. Get something cheaper at your peril, and definitely don't get a TV.
