LUT's are like a transcription file from one color look to another. Actually, they are useful to emulate stock film looks with DSLR footage. It's a fast and cheap way to create film-like videos... without a film camera. If you are recording in V-LOG, you have to find LUT's created for LOG. Right now i'm using LUT's from Color Grading Central for FCP X. Have a look, they are really nice.
Another choice is to grade with DaVinci Resolve 12. Free and amazing video editor.
