Fujifilm GFX100/Fujifilm GFX100S: 16-shot high-res mode looks like crap

re: pixel shift and multi-shot high-res mode
Definitions as used here:
pixel shift= 4-shot capture acquiring an RGGB sample at each photosite using full-pixel sensor shift
multi-shot high-res mode= shift using fractional pixel shifts, typically 8 or 16 exposures
UPDATE: no word yet on whether the Fujifilm GFX100 firmware update 3.0.1 (“Stability of operation for pixel shift shooting is improved”) succeeds in delivering more than the worse than lackluster results I’m seeing.
See previous discussion of Fujififilm GFX100 16-shot mode.
I’ve had a chance to look at some multi-shot high-res mode raw images from the Fujifilm GFX100 sent by reader Alfred C, including a still life studio image.
The results are singularly disappointing in (a) not having any more real detail than a single capture, and (b) showing digital artifacts.
And that’s a still life with fixed lighting. Outdoor images are hideous, with massive out-of-register color pixels.
Sad to say, Fujifilm has screwed the pooch with its 16-shot multi-shot high-res mode science fair project. What was wrong with giving us a usable (for static subjects) 4-shot pixel shift like Sony and Pentax? How can a company as talented as Fujifilm ship a feature that is total crap? For that matter, why isn’t PDAF banding their top priority, since it’s the #1 image quality flaw in the GFX100/GFX100S.
Compared to the intelligent Panasonic S1R multi-shot high-res mode it’s a complete joke, and it makes the Sony A7R IV pixel shift mode (4-shot) look great by comparison, because at least the Sony algorithm works beautifully for static subjects.
Even the low end cameras can do far better: the Olympus multi-shot high-res mode of the Olympus E-M1 Mark II and Olympus E-M5 Mark II are excellent in still life capture.
