Yup, I've done the test too, Pixel 1 vs 80D and more recently Pixel 3 vs a7 III. However I think the scene you chose is an outlier. Most scenes do not have such wild DR to capture. Such a scene is the Pixel's strength.
On an a6000 I've have shot that with highlight priority metering and +1EV of exposure compensation and then pulled the highlights down in post and pulled shadows and midtones up.
However I'd be willing to bet the default profile in DxO PhotoLab would produce an image from your raw that looked just like the Pixel 2's only with more detail. DxO's smart lighting algorithm is pretty excellent with no user input.
Here's an a7 III vs Pixel 3 Night Sight (basically HDR+ without any time constraints) shot in a scene that plays to the Pixel 3's strengths. The a7iii shot was just processed through the standard preset on DxO PhotoLab 2. If you look closely the Sony shot is clearly better, but at web sizes they look fairly interchangeable.
Also as far as getting that Pixel style tile&merge tech in camera, computer power needs to catch up first. The a6000 can't read images from its sensor fast enough do what the Pixel does (Pixel uses a stacked BSI sensor like the a9 and only has 12mp to deal with on a physically smaller sensor). The growth in processing time required going from 12mp to 24mp isn't a simple 2x linear, its more like 4x. You need both fast readout speeds from the sensor and an SoC that can sustain fast image processing of multiple 24mp frames without making the rest of the camera unusable.
