Lovetoplant, no, I like to eat my persimmon when they are hard/firm.
Both of those fruits in the 3rd photo are still hard and crunchy. The pollinated one (brown inside) tastes very good and sweet, but the non-pollinated one is very bitter and astringent. If you want to wait until the non-pollinated one gets soft, then it is supposed to lose most of the astringency. If they are not pollinated, I just cut them open and then toss them out, so I need to graft more Chocolate and other varieties that will have male flowers to pollinate the Hyakume next year.
