PS4 Pro will probably run UHD Blu-Rays via an update in 2017

Well depends how they encode the video i guess if they use H265 there is no valid reason as to why a movie should be over 50gb lol. Anything larger is just being lazy at encoding.

So in theory a firmware upgrade could potentially play dual layer discs.

Unless there is some sort of mechanical restriction when reading dual layer UHD discs.

Makes sense for 3-4 layer discs for this not to work.

No. HEVC roughly cuts the size in half but you have 4 times the amount of pixels. Nothing being lazy here.
