Yeah, I understand that Sam. I do see even marginal improvements in most 4K titles though, and getting the code will remove a disc form my shelf. Thanks for the heads-up.
EDIT: The bigger issue, which I just discovered, is that this is a Lionsgate release. Apparently it's not available digitally in 4K yet, so redeeming the code from the 4K release only grabs you the HD version. Crap.
