It doesn’t make sense for the many reasons that I’ve stated. Do you blindly accept everything you hear at face value or do you apply logic and question things?
It's very clear that your home theater would be better served by a Strato C (or S). You spent more money than you needed to, and ended up with a lesser result. And, this was due to a known limitation that was insufficiently publicized. There is some blame to be had on K's part. Regardless, you're left with frustration and (for you) a lesser home theater solution. Seriously, I hear you and I get it. That completely sucks, and should be acknowledged. I would certainly reach out to K and your K dealer and see if there's anything that can be done to improve your situation.
Regarding the forum and these posts, I think people are struggling with the notion that K somehow had better choices readily at their disposal and didn't make them in order to save a few bucks. I think that can be dispelled if you look at what's happening with HD compatibility on the V.
K is burning thousands of man hours and burdening their content team for months on end to address a separate chip limitation. How much is that costing them? How much of the profit from new and expanded sales are being chewed up? They're frustrating new owners by not having sought after HD titles available, and annoying veteran owners by not delivering new 4K titles because the team is busy.
It's a rather large cluster, and I have to imagine K did everything they possibly could to avoid it. The idea that somehow a better chip was just sitting there for selection, but cost a few dollars more, doesn't pass the smell test.
What does pass the test? Chipmakers limiting features to manage costs. Across the industry we're seeing new devices missing features from older devices. Do I think that someone, somewhere decided that a 4K GUI wasn't worth the cost of support? Certainly. I just think they worked at a chip manufacturer, and not at K.
Some of the frustration of buying a Strato V instead of a Strato C (or S) may lie at the feet of K. Please reach out to your dealer. The frustration of Strato V limitations likely lie at the feet of chipmakers. I believe K stands beside you in this frustration, not against you.
