Just trying to get a firm position on this, are all IPS panel types of the same quality?
Pretty much since (to my knowledge anyway) LG has been the source of all the IPS panels on the market. Their QC has been less than stellar over the years. All the issues people complain about with IPS panels are nothing new and have plagued LG IPS panels for years now. Doesn't matter if its S-IPS, e-IPS, H-IPS, AS-IPS, etc.
