I’ll tell you the answer 4k HDR.
Well it’s a good educated guess the only reason to do a new scan is really to add the HDR. You need to scan it in HDR to get the benefit of HDR.
But there would not be much point in that unless they sort out contrast color issues also anyway.
Just saying It could be good, really good. If it’s done right. It could also look totally different from what you are used to.
