>The issue with combining images together is that it works for static objects well, but if things move -- it does not. So low-noise digital sensors still seem to offer much better results

The problem is mirroless/dslrs have much bigger sensors with slower readout, and much worse DSP capability than say an iPhone. They also use it much more conservative that a mobile phone marker too (which just cares to get a nice looking image to the casual user, not for fidelity and ultimate control).

So, mobile phones for low light can still get better post-processing results for moving subjects compared to any mirrorless/dslr "HDR" mode, through quicker intermediate shots taken and combined, and more DSP resources to devote to the task.

(Samsung, Google, and Apple also have much more money than Sony and Canon to spend on state of the art AI/ML applied research and DSP developers).
