I've noticed that there's quite a few threads on this forum regarding whether various older MacBook Pros work with different combinations of the LG UltraFine 4Ks. I wanted to add my success story: I have a late 2013 model (MacBookPro11,3 with GeForce GT 750M) and I can confirm that it does indeed work with dual 4K UltraFine displays. The displays are driven at the full 4K resolution at 60Hz. My setup is as follows:
  • Late 2013 MacBook Pro w/ GeForce GT 750M
  • 2x LG UltraFine 4K 23.7" (the newer, 2019 model)
  • 2x Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 adapter
  • 2x Thunderbolt 2 cable (1x 0.5m length, 1x 2m length)
Output of System Information is as follows:

Thanks! Could it be that this same macbook model would be compatible with the 2016 Ultrafine 21.5 4096x2304 monitor?

You should be able to get the monitor to run at 48 Hz (my Late 2013 15" retina MBP with integrated Intel Iris Pro graphics does it just fine - 60 Hz isn't possible due to hardware constraints), but you need a Wacom Link Plus to go from Displayport to USB-C. (No Thunderbolt stuff!)
