In a discussion some questions come up and I got the tip that there may be help here
Are there an information in an Pentax K5 PEF file which can't be found in a pentax K5 generated DNG file?
Does the adobe dng converter transport all metadata from the pef to the dng or gets metainformation lost?
Off the top of my head I don't know the answers to these questions. You'd have to compare the ExifTool outputs to see.
But in general, I do not trust the Adobe import of maker note information for 2 reasons:
1) It is known to lose information for some camera models
2) The information is reformatted to a proprietary Adobe format that nothing but ExifTool (as far as I know) can read

Thanks, then I got the information i want to know.
It is a very important, when you say, the format may loose some information.
And that there is only one tool to read it, that is not enough.
The second thing is, how can I dump all meta information of a pef or a dng file?
That means all, except for preview pictures and all Raw-Data.
The command I recommend is:
exiftool -a -u -G1 -w txt FILE
where FILE is one or more image file names or directory names.
This command will produce an output ".txt" file for each input image.

Is there any information wether a dcp-profile is embedded in the dng-file?
You could look for some of the DNG Profile tags (ProfileName, ProfileToneCurve, etc).
See the EXIF tags documentation (https://exiftool.org/TagNames/EXIF.html) for a list.
