'Dynamic' Pixel Shift

Doubt that, the dynamic ps shots have artefacts and aliasing on lines that are inexistant in the normal and classic pixel
Shift shots.

What is certain here is ibis can't achieve a pixel perfect alignement of the shots either you are moving or not (you can see that on most details close to a pixel size compared to pixel shift shots), but rather stabilise the 4 shots and use your small hand movements to do the "pixel shifting" exactly like in standard super resolution stacking.

The advantage here is it done in camera, the disadvantage being you don't have any control over the number of samples or the stitching.

That said the HDR mode already did pretty much the same thing with 3 shots, you already have the increased gain in resolution, reduced noise and increased dynamic range, but also the artefacts on pixel level details (especially lines). The new dynamic PSR does seam to have a better stacking method, looks like mean or medium stacking with a touch of sharpening, that the HDR shots lacks.

I don't know why you keep bringing up HDR - other than the fact that they both work on multiple exposures I don't think they have anything to do with each other.

That's because HDR mode stitch the 3 pictures and sample multiple shots using the camera shake and stitch them like the Dynamic PSR :

"The camera closely analyzes four captured images and detects camera shake during handheld shooting before synthesizing them"

In both case the shots are aligned in camera, maybe the Dynamic PSR use the gyro to do that where the HDR only analyse the shots after, but that is still picture stacking.
