Yes, we have had this discussion
I will concede on DVD compared to a good 35mm print. However, a few counterpoints:
-no compression artifacting.
Artifacting can be distracting, but a well authored Blu-ray should not have obvious artifacting. Much of the time artifacting is visible because of poorly calibrated monitors (jacked up contrast, brightness and sharpness) and the wrong gamma settings.
-no 2:3 pulldown.
There is no 2:3 pulldown on 24P Blu-ray.
-No judder (from the pulldown).
See above.
-no aliasing (you still can't convince me that there's not some ocassional aliasing even on well done dvd transfers if there's a really tight pinstripe pattern on someone's clothes or the like. I still see it from time to time).
Will concede aliasing, but still maintain that has more to do with poor deinterlacing, poor authoring, or poor upconversion to non-native resolutions than being inherent to the DVD format. Blu-ray should not suffer from these problems unless poorly scaled to other than native resolution.
-film has a warmth that I still haven't seen reproduced by any digital projection to date. I realize this is really subjective, but I know I'm not the only one who thinks this. Digital projection in movie theaters still feels cold & sterile, for lack of a better word.
Interesting, in that people say the same thing about digital audio, where the truth is that digital audio is much closer in sound to the original source elements than any analog delivery format (and yes, that applies to digital audio mastered from analog source elements).
If one compares an actual 35mm film frame to a 2K or 4K high quality digital scan of the same frame, they are essentially indistinguishable. That softer, "analog" quality to film projection (or analog audio) is simply a pleasing artifact that film projection (or analog audio gear) creates. However, it is actually distortion (pleasing though that distortion may be).
