I've been wearing glasses for most of my life due to nearsightedness, and I don't care at all about density anymore. Even 4k is a bit luxurious. As I get older, it matters even less. I simply cannot tell the pixels apart anymore.
The real limiting factor is display size at the current densities. I can always use more real estate. A 49" super ultra wide is still fairly expensive (but getting cheaper quite quickly) even at not 4k densities.
Even with phones, Apple pretty much nailed it with the Retina display. The only thing I notice with newer displays is that the colours are better. In terms of smoothness, I can't tell the difference.
