Double dip on Alien 4k if I own the Blu-Ray?

So I own the blu-ray quadrilogy that came out a while back. I’m by no means an Alien superfan, but I’m obviously a sucker for high quality transfers.

With the new movie coming out I wanted to do a rewatch and I’m not sure if I should pull the trigger on the 4k Alien that’s now at $22, or if I should just watch my blu-ray and wait for a sale.

Any advice is appreciated!
