Dry age time on prime ribeye

[Bob Moore]

I am also in the tail end of dry aging a Prime Rib roast, only I have an issue. I was out of UMAi bags so I used regular vacuum sealer bag, and much to my surprise the roast is not forming the hard outer shell that is shown in the video. It has been in the fridge since right before Thanksgiving. My questions is, will it still be good to eat/ how will using regular sealer bags affect the roast?
I appreciate any help/comments.

Thanks,
Bob
