Please help settle an argument! 2k vs 4k scan on BD

Long story short, can't figure out who is correct on this one. I'll spare you the details on that front.


You have a pristine 2k scan of a film and a pristine 4k scan of the same film. If they're both encoded down to the same amount of pixels for Blu-ray, 1080p, will the 4k look any better?

I'm not talking about going from a poorly done 2k to a brilliantly done 4k; I'm saying both scans are top notch. Will those extra pixels in the 4k scan actually make a difference if they get downsampled same as the 2k?

Thanks in advance for any help on clearing up this issue.

The 4k starting source for down-conversion should have greater detail (more effective resolution) for these reasons ,providing the proper down-conversion algorithm is used. -- John
