First of all, deciduous trees should not be heavily wired. You really can’t move thick branches with wire. Thin, young branches, yes. The technique is the wire the thin, young branches, the ones that have not lignifed yet, and set them into position. Once they are lignified, remove the wire. That only takes a month to 6 weeks. Remove the wire before they start to scar up.
On your trees, they didn’t do that. Is it the end of the world? No. Those branches will heal to some extent, but the other thing I see is they are long and taperless. Which is a problem no matter that they have wire scars. What really needs to happen is some cut backs. Cut those branches back, and regrow them.
The “value” in those trees ARE NOT in the branches! The value is in there bases, the root over rock portions. The entire tops can be completely regrown in a year or so.
Stop stressing over the wire scars, and look to determine how the canopy can be, and should be restyled and regrown.
Don’t like the wire scars? No problem! Cut them off and grow new branches! Bjorn posted a video on YouTube recently where he showed a nice tree that had some wire scars, and he said the best remedy was just to cut them off and start over. Those are fast growing trees!
