I do still see complaints in Amazon reviews. What's strange is that only one reviewer out of hundreds might mention it on various cases. So I don't know if the case manufacturers have gotten better or the low light capabilities are now so good that people don't use flash often enough. Or don't realize that what looks like improper exposure is actually the problem you're talking about and not a problem with the case.
I have seen the occasional remark that some cases that are strongly colored cause pictures to come out tinted as well.
I've been using black cases for so long I personally haven't run into any problems in years.
