Can blown-out white areas in a RAW photo be recovered, or only retouched?

I have close-up photos shot as RAW/DNG on a phone, and some areas are badly overexposed—nearly pure white. Basic adjustments in Photoshop and other editors don’t bring back detail, which suggests there may be little or no image data left in those highlights. Are there any practical ways to recover or convincingly retouch these blown highlights, such as RAW recovery, blend-mode tricks, content-aware fill, or AI-based tools? If the detail is truly gone, is manual reconstruction the only option?

If the data is gone, it's gone. Any area that reads as 255,255,255 contains no information at all. It's blown-out.
Take a really simple example as demonstration…
We take a screenshot
Then we lift the exposure until none of the name remains, though the other details are still vaguely visible.
Then we save that, so we have no 'undo' steps. Open the new copy & try to recover the original data
It's gone. Nothing we do can recover the name.
It's exactly the same with a blown-out area in a photograph. You have a better shot from RAW than jpg, but once it's gone, it's gone.
Sorry, the extra black lines on the first two images is a result of my inaccurate screen-shotting from inside photoshop, not part of the experiment.

If those areas are truly clipped to white, the original detail is gone and cannot be recovered. In image terms, once highlights are blown out to pure white, there’s no hidden texture left for Photoshop or any editor to restore.
You may still have a little more latitude with RAW/DNG than with JPEG, so it’s worth checking highlight recovery and exposure controls first. A blend-mode approach such as duplicating the layer, setting it to Multiply, and limiting the effect to only the brightest tones can sometimes reveal a bit of remaining texture if the highlights aren’t fully clipped.
But if the data is completely lost, your options are retouching rather than recovery. Tools like Photoshop Content-Aware Fill or AI/generative features can invent plausible replacement detail, and manual painting/cloning may be needed for the most important areas. That can look acceptable, but it is reconstruction, not restoration of the original image data.
