There's probably a sweet spot for how much out of place one looks, which might be mostly down to preference. But to me that sweet spot is looking unique without looking jarringly out of place.
A group photo where you are the only one using an antiquated shader might make it look like the map's lighting (or yours) is broken, rather than you having made conscious choices on how you want to look in that lighting.
On the other hand, a group photo of 20 default Merinos with just a slightly different hair shade is boring, too.
