Daas Yochid,
On the Aruch Hashulchan you cited, he does understand an issur in r’iyah but this is limited to makomos mechusim. So it would still depend on the norms in the time and place. Furthermore, I think that by r’iyah he does not mean incidental (he specifically says that there is makkos only when there is kavanah) but rather where there is intent for r’iyah but not for hanaah. In contrast, histaklus of mokomos megulim is only assur if there is intent lhonos.
