So is the assembled product really named like that?

Samsung S0FEF01-M AMS605DK01?

I would more expect the compatible strings to be excluding the DDIC
name, like:

samsung,ams605dk01

...but it's not like the vendor is helping us here, so I'm practically
fine either way. They are clearly using the S0FEF01-M display
controller.

Yours,
