I just looked back to my K10D captures, which for the first few months
(until LR 1.0 was released in Feb or March 2007) were all captured as
DNG files. All the lens data is there, but for 43 files (out of 5500);
all of which are PSD, JPEG or TIFF files where I presume the EXIF data
was stripped.

I do recall that for some of these earliest K10D files, I had to tell
LR to "Read metadata from files" as the Lightroom v4.1 (Public Beta)
that I'd originally been using didn't read in the LensType parameter
correctly on the K10D's DNG files. All LR v1.x versions did.

ALL versions of the DNG specification since LR 1.0 was released
capture all of the data in the native RAW-PEF files.
