About 3DL
Autodesk's Lustre and Flame made the .3dl LUT, and Nuke, DaVinci Resolve, Premiere Pro and Photoshop read it too. LUT packs often ship each look as both a CUBE and a 3DL.
A 3DL is plain text: a first line of the steps along each axis, like 0 64 128 and on to 1023, then a line of red, green and blue for every point of the cube, as whole numbers of 10 to 16 bits, blue changing fastest.
Filepeek works out its size and bit depth from those numbers, and shows a chart of skin, sky, foliage, grays and every hue through the LUT, the chart as it was a page away. Drop a photo with it, and the photo shows through the LUT too.

Questions
How do I preview a 3DL on my own photo?
Drop the photo and the 3DL together. The photo shows through the LUT, and the photo as it was is the next page.
Should I use the CUBE or the 3DL from a pack?
They hold the same look. Take whichever your app reads: most take CUBE, and Autodesk's tools and some monitors want 3DL.
Why does my 3DL look wrong in some apps?
3DL files differ in their size and bit depth, and an app that guesses them wrong washes colors out or burns them. Filepeek works both out from the file's own numbers.
