P: Denoise AI and Pentax K3 MKIII DNG files - not working

Tried indeed the pentax image linked to above by @digitaldog in yesterday's Lightroom release and indeed enhance is not doing anything for the luma noise at all. In fact the "enhance" image is worse than the original. 

Camera Raw 16.0 has been released, no improvement...

Any update on this for Ricoh + Pentax DNG ?

Add the Pentax KP to the list. Same issue here.
BTW I'm using PEF, and so it doesn't seem to matter which of the two available RAW-Formats you use.

Actually, I may have gone off half cocked. While not a lot seems to be happening at relaitively "low" high iso settings - 4000 and maybe up to 10,000 - it seems to be doing a reasonable job when you hit outrageously high iso settings like 128,000 (in my case). More investigation necessary!

Version 15.5.1 and still nothing for one of the best cameras out there. What a shame.

Unfortunately, I have the same problem with my Pentax K-70 (which might have the same or a similar sensor to K-3iii). I realy hope there will be a fix for this. Pentax is Adobe standard DNG-files, which there are reasons for Adobe to encourage. 

No changes in Camera Raw 15.5 which was rolled out today... there is some reduction of color noise as before, but no luminance NR at all with my K-3iii raw files.

Hello,

I have an issue with RAW pictures of my Pentax K70 and the new KI Denoise function.

If I select the image and start the process, the noise isn't gone away (also movement of the slider doesn't show any effect). If I take the "same" image taken by my other Pentax K-S2 there is no problem.

I tried it with all combinations of the Raw settings at the camera (PEF or DNG and sRGB or AdobeRGB) - nothing changed.

I've seen the hint about "Bayer- und X-Trans RAW-Pictures", but I cannot find anything about the Raw pictures of Pentax.

Maybe, somebody has an idea what going wrong.

I have the same issue with my Pentax KP. The same LRC install/version works as expected (great NR) with the K-50 I have, but not the KP.
