CRU creates software overrides. It does not affect the monitor, so it would not transfer over to the PS4. The manual for the monitor says Ultra HD Deep Color must be on to enable 4K @ 60 Hz.

For PC use, you should not need to edit anything with CRU to get 4K @ 60 Hz. It should already be defined, usually as a detailed resolution and/or in a TV resolutions data block in the extension block. If you're using DisplayPort, you should not need an HDMI data block.

ACP/ISRC is Audio Content Protection/International Standard Recording Code. 30-bit deep color is 10 bits per channel (bpc). HDMI always supports RGB. 4K @ 60 Hz with RGB or YCbCr 4:4:4 requires HDMI 2.0. HDMI 2.0 requires both the HDMI data block and the HDMI 2.0 data block. Both should already be there when using HDMI if the monitor supports HDMI 2.0. HDMI 2.0 monitors usually define 340 MHz TMDS for the HDMI data block and 600 Mcsc TMDS for the HDMI 2.0 data block. These basically define pixel clock limits.
