Following the thread (that I can't find) that said that .icc Profiles were lost, with an upgrade iOS, and using Epson SC P700, my solution was quite simply to select your printer and use the cmd key, 'reset the printer' and then add it again. I would also suggest that all Epson Drivers, software and so on are installed. I think the mistake I made was to connect the P700 pinter to my mac book pro, then install Epson drivers and associated software. That did not work. Install the S/W, then add the printer, and use the dropdown for your connection type (wifi/eth) to add the S/W of the install. This worked for me and I did struggle with it for a few hours. All.icc profiles are availalble that I need anyway - hope ths helps those that need it. 😉
When Epson profiles disappear from "Photoshop Manages Color" it sometimes needs fixing manually:
Epson printer profiles are missing in Photoshop manages color in the print dialog (Mac)
To use "Photoshop Manages Color" properly (to make accurate prints) you need access to the printer manufacturer's paper specific profiles since you need to select the relevant paper profile in that dialog.
Using "Printer Manages Color" should work for Epson’s own papers, as long as the printer driver is correctly installed.
Printer Manages Color [based on the media type selected] calls upon ICC printer profiles from a different installed folder*
[*usually a hidden one, this is so they don't get deleted inadvertently, more on that and how to find them below].
Epson ICC printer profiles may be missing in Photoshop after updating macOSX. This issue started with Mojave.
