Helmets in a lot of games are complete Derp. I too wish there was a toggle helmet view option.
I do not like the option to conceal a worn helmet without losing the benefits of wearing it. If there are no benefits... then just take it off.
** This would extend to absurd looking magical items and clothing ~worn (and tolerated) for the enchantments they confer. If one wants the incredible armor bonus from the silly pink and blue polka-dot paisley leather cap... one has to wear (and been seen wearing) it, (or it shouldn't work
*).

I'd consider it a blatant cheat otherwise. The option usually exists for any non-cursed item in most RPGs to simply not wear it.
*And if its cursed (and stuck on them), then all the more reason for it to be an annoyance that must be endured until they can (in a game legal manner) get rid of it.
** But perhaps the object could be enchanted (at significant expense) to be made permently invisible?
(But I would expect the the game to make the 'world object' permenently invisible as well; and so it becomes a risk to ever set it down.)
* Spoiler Who knows, part of that armor bonus might be because it's so silly and distracting to an attacker.
