I newly upgraded to Mac Studio running Monterey OS 12.5. Profiles are stored in Color Sync folder for both the root HD and the user. The printer is Epson 3880. All profiles, including canned and custom appear and are available in the Photoshop print dialog. However, only the canned profiles appear and are availble in Lightroom. I've tried renaming them and have deleted and reinstalled the printer. Nothing helps. Any suggestions?
ICC profiles have an internal name (generally use for in-application display) and an external name (that’s the one you see in a folder), if you rename them you're only affecting the external name - then the new name does not show up in applications.
Many third-party media profiles have different internal names, don't ask me why!
I suggest you open a missing profile (just one) in the colorsync utility,
check the internal name then look for that name in Photoshop
I renamed this profile in the finder to: '39-47 renamed.icc',
You can see that in the header of the utility below,
you can also see in "desc' that the internal name is still "39-47.icc":

Good point about the names. But I highly suspect it's something else as the OP sees the profiles in Photoshop but not LR which is a head-scratcher. I've heard of issues with missing profiles in the past, but they were missing in all Adobe products if memory serves me.
