A lot of phones bracket their images to get their DR. The night mode on some phones is them shooting multiple exposures in a short burst then blending the best parts of each image together in real time.
I use LR mobile from time to time to shoot DNG and I've found my XS Max struggles in anything even remotely low light. I went out to do cityscapes at dusk with my A7III and even though I was using HDR DNG mode, it was noise ridden and looked horrible on the iPhone. It's main advantages all come from computational processing within the camera so when you use these 3rd party apps that don't utilize these features it really shows it's weakness.
I would be curious to see what JPEG's on an actual ILC would be like if the same computational techniques could be built in the cameras firmware.
Yes the pro raw is basically taking an HDR, flattening the base exposure, but baking the captured tonal depth into a raw file. Its an interesting concept. I always feel that the default hdr on phones is way too strong, so itd be nice to quickly tweak the tones in the phone.






but I thought I'd share this:
