About LRPREV
Lightroom Classic draws a preview of each photo it shows, with its edits, and keeps it in the catalog's Previews.lrdata folder as an .lrprev, named by an ID and a digest of the preview, in folders of its first letters. Each file holds the same picture at several sizes, from the thumbnail up to the size of a Standard or 1:1 preview, after a header naming them.
Nothing but Lightroom reads them, and when the originals are gone, on a dead drive or a lost card, the previews can be all that's left of the photos. They're JPEGs inside, in Adobe RGB with no profile saying so, so pulled out by hand their colors come out dull.
Filepeek opens the biggest picture in the file in your browser, in Adobe RGB's colors, in the image viewer. Zoom in, and Export saves it as JPEG or PNG. Dropped with its catalog, each preview stands in for its photo under the photo's own name.

Questions
Can I get my photos back from previews?
Yes, as big as the previews were made: 1:1 previews are the photo's full size, Standard ones about the screen's. Drop the Previews.lrdata folder with its catalog to see every photo under its own name, and save them.
Which photo is this a preview of?
Its name only says which entry of previews.db it is. Drop it with its catalog and Previews.lrdata, and Filepeek puts it under its photo's name.
Why are its colors dull in other apps?
Lightroom keeps previews in Adobe RGB without a profile saying so, and an app that takes them for sRGB shows them dull. Filepeek gives them their Adobe RGB colors, and its saves look the same.
