Which version of DNG did you select in the CHDK menu?. Only 1.1 does bad pixel correction in the camera.
Whops! I have selected 1.3 thinking that that newer is better!
BTW, it there an other way of doing bad pixel correction that is better?
It depends on what software you use. If you can tell your software to fix 0 valued pixels, it will probably do a better job than the in camera badpixel.

I don't have photoshop so I don't know. Disappointing Adobe doesn't do the right thing with their own file format In the past IIRC you needed a plugin to open DNG at all (adobe camera raw?) but google suggests that's not the case any more. I'd expect lightroom to do the right thing.
That should happen automatically - I just tried a quick test and PC CC (2015.0.1) correctly removed the bad pixels from the DNG file.Can you upload your DNG to a file share site (e.g. dropbox, google drive, etc) and post the link here.Phil.
Unfortunately I deleted the image from my kitchen but here is another image from yesterday. Lots of green pixels and even some blue ones in the orange koi carp The file is DNG 1.3https://dl.dropboxusercontent.com/u/66272586/CRW_6315.DNGVery interesting to see if it works for you. I also have PS 2015.0.1
