I feel like this is the argument people make every time Mesa releases a new Mark series amp. "It doesn't sound like the IIC+!" Then Mesa tries to explain "you know, we tried several real IICs and then made something that sounds like those." "But it does not sound like my IIC+!" the nay-sayers cry.
Maybe they are right, but at the same time people enjoy the convenience of not having to lug a big, expensive rack unit around or can enjoy all the other tones a Mark V for example has. I enjoy a nice tape delay, but have no interest in owning a real tape echo device. So for me it's irrelevant if it absolutely nails every aspect of it because all I care about is that it sounds good.
I've started applying the same approach to digital modelers where it doesn't matter if it's 1:1 authentic as long as it sounds great to me.
