Should you make your dating app picture 6/10 or 10/10?

I was listening to the radio this morning and they were talking about dating app pictures. One lady called in to say that she fully believes in taking a dating app photo that presents her as maybe a 6 or 7 rather than a full blown 10/10. Her theory was that by posting a photo that wasn't super great, she left room for her to make herself look better through better hair/make-up and have her potential date be blown away that he got more than he bargained for when she shows up for their first date.

Good idea or totally stupid?

I'm not talking about digital alterations, only things like doing hair and make-up in reality as the caller wasn't talking about photoshop or filters. Also this is some random photo I found, not of the actual person. Didn't know how else to illustrate her point.
