Was the Uncompressed RAW feature been removed?

[UltimaGaina]

Can someone clarify why the Samsung S20 series (including S24U) stopped generating uncompressed RAW files sometime in Q1 2023?

In Pro mode, we now have JPEG compression in a DNG container. It is a 12-bit JPEG.

Expert RAW has the same JPEG compression (on 16 bits, probably because of HDR) for S22U and S23U, while on S24U it shows as "Unknown (52546)" compression. According to an article I found on Samsung India, it is said that this is a new JPEG XL compression.

Why not offer the option to get again (as we had before Q1 2023) truly uncompressed mosaiced RAW, which works with the Lightroom Denoise AI algorithm, instead of the current demosaiced compressed Linear RAW, which doesn't.

I wonder if the next beta release will fix it or if reporting it in the beta forum will get some attention.

Lightroom can De-Noise JPG XL now, but that won't bring the dynamic range back.

JPEG-XL encoding is super slow as there is no hardware support.

Despite of compatibility and dynamic range (not the fault of JPEG-XL oer se) this is a mayor drawback

Any news on this?

@rawshooter do you have any news on this?

I did not participate in the UI7 beta and no one provided me with files.

I also won't get the 25 because of the removed remote shutter function in the pen. 

So I have nothing to test until UI7 its released for the 24.

The bluetooth pen is sold separately for S25U.

Just a rumor from one guy not really affiliated with Samsung, unlikely.

But just in case I ordered one before the discounts expire, will send it back if this rumor is false.

[UltimaGaina]

It is explicitly mentioned in an official Samsung blog.
