I have a 40in 5k (32in 4k, but wider). IMHO, 138ppi is the bare minimum, but it really depends on a person's eyesight and preferences.
I would love a large-ish ultra-wide with > 160ppi. One day, maybe, that being said, by that time those things will exist and be reasonably priced, my eyes might not be able to appreciate the difference.
