You're absolutely right that most men could stand to improve their profiles. However in the article the writer mentions how the photos she saw seemed designed to fit some template of what is supposed to be attractive, and that she was a little wary of how professional they appeared, so this can go both ways. Overall, though, it seems far better to have higher quality photos even if they appear staged.
One of the biggest challenges, however, is that the nature of these apps means that to 'get a good feel for your real personality' people must somehow get that across in only a few seconds before the person on the other end swipes on to another profile. With margins like that, and so little to work with, it is daunting and seemingly impossible to try and write something compelling enough to capture attention in a consistent way.
If I match with someone I want to be able to convey that this person gives me a strong vibe of compatibility. It makes the next steps of conversing and meeting a natural conclusion. I don’t think you can do this if you don’t know what you’re looking for or who you are or what life you’re trying to live. But this is all very straightforward if you can make it clear you’re looking for something specific - in my case a spouse to raise children with. Without a goal the path is not clear.
If anything money should be spent on improving the profile itself (you could hire a professional photographer to take some "candid" looking nice photos of yourself + go to a higher end hair cutter, get your clothes tailored, etc etc). All of these things would probably also help you in real life. Worst case you have some great LinkedIn photos or something to send your family and some great fitting clothes to wear to dinner with friends.
