I confess (rather ashamedly) to having used wall hangers for my (then) two guitars for a few years in the past. (in my case the hangers were made from coat hanger wire!)
One guitar - a relatively inexpensive student type guitar - suffers no adverse effects at all and I still hang it that way.
The other (I say shamefacedly), a 1968 Hermanos Conde, is a very good guitar indeed and has Brazilian rosewood back and sides. The sunlight has lightened the colour of the sides and bleached out the signature and date on the label (you can just make out the ghost of the ink if you photograph the label and manipulate the image). Additionally the changes in humidity certainly didn't help the back. As we all know Brazilian rosewood it liable to split if you look at it the wrong way! (There were long standing small cracks which would probably have developed anyway, but being subject to changes in humidity didn't help.) - So I have learnt my lesson there.
Incidentally. the Hermanos Conde is now (temporarily) in the loving hands of Alastair McNeill and, luckily, he believes that some of the "bleaching" effect is due to the french polish being affected - so he hopes to at least partially restore the depth of colour.
(I currently use a room humidifier to maintain a RH of roughly 45%-48%. It works, but I would love to find a room humidifer that works well and is virtually silent
