Do you know this for sure? I'm sure Sony may have forseen this and acted accordingly when making the Pro. Then again, I don't know that for sure so I won't make baseless claims. Not saying your claim is baseless btw.

yes. There are two main things to UHD Blu-ray. the codec used and then capacity of the disc. 

things like the codec  can be patched in via firmware but doing so isn't enough for sony to claim their consoles can play UHD movies. That's thanks to the capacity.

As it stands a typical BR movie can be as big as 18-35GB. That's all well and good for the two layer (50GB) discs the drives in the PS4/PS4pro has. the average UHD movie goes up to 45-80GB. so if sony patched in support for them there will be a good number of discs that won't just work (basically any disc that uses more than 2 layers). 

So this isn't something that Sony can just add in via a software update. There is also the matter of the drive speed. UHD BR require a higher nitrate than what the 6x drive in the PS4's can do. You need at least 8x..... (not too sure of this last part tho)

Its not just a codec thing. Its an API thing.

Sony would update their API and their media app to allow it to work.

Its the same thing for HDR its the same type of data management that happens.

I have heard reports that the PS4 blu ray is capable of reading quad layered blu rays i believe this was known prior to launch even and people were wondering why Sony didn't use it for games.
