Am I missing something or is this supposed to be in another tier of image quality?

Ilford Delta 400 pushed two stops to 1600 ASA in a 1970s Asahi Pentax SP1000 was always going to produce… artistic results, requiring as much imagination as acuity to appreciate the subject. (Read: see past the blur.)
A 36Mp camera is not enough to best a 4000ppi scanner. You need about 60-70 mp to resolve the detail of a scan to similar level .
Even a layman can see the difference at 100%
For most films, anything beyond 4000 DPI is just going to help resolve the grain particles or dye cloud shapes. You have to be shooting slow fine grained BW with the best lenses to need more.
Well, as I mentioned elsewhere old fashioned Kodachrome resolves ~100 lines/mm and some newer color emulsion are considerably higher, and of course B&W ones have even higher resolutions.
Given that a 35mm frame is 36x24mm even Kodachrome achieves 8.64 megapixels. OK, let's allow for an overgenerous Kell factor of say 0.8, this figure will drop to ~6.9 megapixels. Given the ready availability of emulsions with higher resolutions, especially the best B&W ones then a figure well in excess of 5 megapixels is relizable in practice.
Of course, that doesn't take into account the image chain as a whole, lenses, displays, compression, etc. which would reduce the effective resolution. That said, these days the typical image chain can easily achieve much higher pixel throughput than 5 megapixels before bandwidth limiting so the effective Kell derating factor could easily be kept quite small.
Are there any sample images
If that matters, I’m not sure.
