Asking "is it worth upgrading" is actually a legitimate question in a UL forum.
You could upgrade this jacket and save N grams for a certain cost. For the same money you may be able to save even more weight. Alternatively there may be an alternative to upgrade to that has a greater saving. Also is the jacket even really an upgrade on the previous model.
A forum us a good place to ask such questions, present options and debate the costs / merits.
So, to rephrase your question (making assumptions here sorry):
Is it worth paying for an upgrade on the previous model or would it be better to get something else if you're angling to save a few grams?
My vote is looks like a nice bit of kit but the hoodie arrangement seems like it'd be a bit of a PITA compared to a full front zipper. For me the zipper would justify carrying a few extra grams (but then I'm not a true ultralighter either).
