Perhaps a bit of background on a couple methods, used by various cabinet manufacturers, professional veneerers and common civilians use, in the application of veneers, will assuage some fears.
The suggestion of using an iron tells me: Ohm applies theirs with one of the following, common methods.
Hot Melt:

or: something similar to Titebond Wood Glue and heat:

As you can see from those vids; the judicious use of an iron would be an excellent method, for the repair of weak veneer adhesion.
Seems to me: the high solids (rubber), 3M contact adhesives, we used back in the day, could probably be repaired the same way. Never had to try it though.
As suggested in the third link: keep the temps down to where you can touch the
surface of the veneer, without burning yourself.
If that was the suggestion of the manufacturer; I'd have to assume, they feel whatever finish they applied, wouldn't be damaged, by the iron.
From what I remember of the Ohms I repaired, back in the Eighties: they had a mostly natural, oiled finish (no gloss). Don't know about now.
I'd still use a lint-free cloth, between the iron and veneer, anyway.
It's been my experience: in dry climates, in homes using wood burning stoves or high heat and no humidifier: glues dry out and expensive, antique furniture falls apart too (just a thought, having effected repairs on a lot).
Give it a try, on one of the areas that is mostly out of sight, if you're afraid of the outcome. ie: The rear seam would be a good place to start.
Repairing one's own equipment, can be most gratifying.
ie: Do a good job and you'll get warm fuzzies, every time you sit in front of those pretty Ohms.
