If anything, AI should be extremely capable at demosaicing. In fact, it could be trained easily with the ibis four-shot hr images like Olympus e.a. offer.
Phase One did this already,
years ago, using data from the Phase One P45+ and Phase One Achromatic (same sensor, optical path etc, just with and without RGB filter on the pixel wells). It's one of the ways they made large improvements to the per-pixel quality of the Capture One raw processing algorithms; no additional step of processing required.
From some initial testing of LR's Enhance Details tool...
Detail Enhancement: Meh. Not much improvement, and where there is improvement it's only because LR's starting point is pretty mediocre. In this regard Adobe has added a convoluted step to their workflow that gets their image quality closer (but still, to my eye, not as good as) C1's native raw processing algorithms. This is true of absolute detail and fine lines, but it's even more true of the overall feel of the detail, which feels more organic and natural to me in C1 (again, without the need for a separate processing step).
Color Moire: Meh. The effect is that of locally blurring the color. If an area moire'd with a bias toward red then Enhance Details reduces the speckling, but not the underlying bias. So things are still randomly red or blue or green tinted that should be neutral. This can save time vs manually retouching for a quick-dirty use but for any sort of final use you'd still often need to manually retouch the color.
Luminance Moire: Impressive! In some cases subject matter that was rife with moire is cleaned up
entirely. In other cases the moire is still there, but with a slightly tidier look. In some cases the moire is not improved at all. Overall that's very impressive.
Our experience is that, as you pass ~30-50mp into higher resolution sensors (e.g. 80mp, 100mp, 150mp), the chance of moire falls through the floor (still technically can happen, but
far more rarely). But since most of the world is still shooting cameras in the 10-50mp range and likely will be for many years to come, this improvement in ACR is very welcome and will be broadly useful.
Hopefully as computing power improves and the programming/frameworks behind this tool improve the effect can just be folded into the normal processing chain.
Bias Alert: I'm an admitted C1 fanboy and must be considered biased as my company sells P1 gear.
