PS4 Pro’s inability to play 4K UHD discs is, no doubt, short-lived

It's not about hiding the fact..the HDMi controller inside the PS4 was able to be updated to HDR , because it was 2.0a compliant.

The BD-UHD optical dive is a BDxL optical Drive Sony has indeed a BDxL optical drive inside the PS4..it can read layers past two layers..Sony did not want to pay the licence's for UHD playback, it most likely saved a few $ , without that functionality.. And it's very likely Sony feels no reason to update the Drive for UHD playback, because the HDMi port controller chip has a Upscaler inside..

It's a 6x CAV drive, it's simply not fast enough for 4K UHD discs. Unless they can patch it to spin faster....

1X speed is 36Mbps, 4K 100GB triple layer discs require 128 Mbps to be able to be read for the 4K UHD standard. 6X = 216 Mbps. The drive is fast enough for current UHD standards. The limiting factor is whether or not the beam is narrow enough to read the 33GB layer and is capapble of reading all 3 layers.
