I did go through a stage of touching up hooks, and honestly found it made no difference. Now I don't even touch up pike singles or treble hooks, blunt or turned point on hook change trace or hook link.
Waters I fish I seem to turn points over on underwater features, branches, mussels, concrete. Nothing more annoying than feeling a freshly sharpened hook down, knowing it has not gone right and reeling in a turned over hook.
I've mentioned it in the past about one rig catching a 26 at Merrington during a carp.com social. That same rig caught more fish, think it was another 5 at Hintlesham, until I turned the point overcasting and finding a tree.
The strange thing, if you get the same pattern in barbed and barbless, the barbed appears to the naked eye, more blunt than barbless. It is normally an illusion. What stops hooks penetrating is the barb, exactly what holds it in place. Take the barb down and penetration is improved.
That is something I used to do on many Owner FLB's, the barb on some was brutal.
