You can get the very similar results on the X if you force HDR. You can get even better results by using a camera app that has RAW capabilities. The only real advantage that the Xs has is in video capture with its expanded dynamic range and stereo sound recording.
No. HDR on iPhone X/8 is good in daylight. But it does NOT show shadow details. It only control highlights. It some cases, it may even make shadows DARKER (aka less details).
Now go inside the house (even with decent lighting)...force your X/8 into HDR...take a few pics. What do you see? Sure, highlights are controlled but TONS OF NOISE. Edges get really smudgy. The pic is actually darker vs non-HDR!! And this is why Auto HDR on X/8 does NOT turn on inside the house or less than ideal lighting condition...unless you’re really really close to bright light bulb.
Smart HDR is NOT your regular HDR. Smart HDR is better than ANY HDR program at this time, including Pixel 3. And it is all due to A12.
Smart HDR takes multiple frames. Firstly, the camera constantly shoots a four-frame buffer, so that there’s zero lag when you hit the shutter.
But in ‘smart HDR’ the camera also shoots ‘interframes’ between those frames at different exposures to help bring out things like highlight details AND also a long exposure to get shadow details.
Rather than then simply combining all of those frames into one shot, the neural engine then chooses the best parts of each photo and merges them together. Hence ‘smart HDR’.
In simple terms, it does everything that Pixel is doing...but adds an extra frame for long exposure on every pic. Pixel is able to control highlights but like every other smartphone, the shadows are dark...actually Google likes to crush the shadows (black, no detail) because it uses lots of contrast.
By taking a long exposure, Smart HDR actually recovers the shadows! Shadows are now full of details. This is something that no one else is able to do on EVERY picture taken.
This is why Smart HDR pics seems "flatter" than others because the highlights are controlled (like Pixel) but the shadows are less dark with more details. There is less contrast vs. competition as a result. The difference is that Smart HDR takes a picture that is very much like what your eye balls see in real life! Your eyes/brain actually does HDR and up until now, no camera system is able to come close to what your eyes see.
The cool thing about Smart HDR and Apple A12 is that when you take a picture, it is instantaneous! There is no spinning shutter button or any lag in processing the HDR picture...like you have with every other smartphone. Apple A12 actually DISPLAYS the smart HDR picture on your iPhone display BEFORE you push the shutter button!! So, you know what your picture looks like before you take the picture. Apple A12 does the processing of Smart HDR in REAL-TIME as you move your iPhone around the scene. So, when you push the shutter button, it takes the picture immediately without any further processing or wait.
And like pictures, the video in 4k30 also has Smart HDR...and again, Apple A12 is adjusting every pixel in the video frame for Smart HDR in REAL TIME.
Overall, in pictures, it comes down to preference if you prefer Google Pixel 3 or iPhone XS. Pixel 3 has more contrast but sometimes crushes the shadows into blackness. XS pictures are flatter, less contrasty, but has more details in the shadows.
But in Video, XS is far superior to Pixel 3 and pretty much everyone else. It's not even close.

I'm admittedly not a photo pro but I am a hobbyist. So I definitely appreciate camera improvements and don't deny there are improvements across the board from X to Xs. I do think, even in the video you showed above, that they're minor. As I said, there's nothing that the Xs can capture than the X can't.
Highlights and shadows can be saved on the X if you force HDR (which I always do on my shots).
iPhone 2019 will in turn 'blow the Xs out of the water' by some people (your) standards. But I expect it will be, again, relatively minor.
No. X HDR does not recover shadows. It turns low light shots into crap.
