Exactly, and often those are the best renditions. One of the first rules of photography, avoid harsh light.
And when more light is in the scene, you shoot at high ISO, and your DR at 6400 is pretty much irrelevant, as is most of what's published on DxO.
All I'm saying here, is clean 6400 ISO images could be very useful to me, regardless of lack of DR. I'm not understanding why this is so difficult to comprehend.

I have no images taken with a K-3 or K-5 that I'd use taken over 1600 ISO, so 6400 sounds really good. Out in the blind shooting birds with the A-400, that's the difference between 1/500s and motion blur, and 1/2000s and freezing the wings in a lot of light. And anything I currently take with my 60-250 and TC I should be able to take with the A-400 and TC. IN late afternoon light, or morning light, frequently the DR is well inside the curves even at high ISO. SO while DR is great for landscape when you have a brilliantly lit scene, there are a lot of wildlife scenes where you don't come close to using the full DR of the camera, even at high ISO.
For a lot of wildlife, DR is not really a critical component.

When comparing sunsets, and other low light high DR situations, with my K-3 and K-5 , DxO has been bang on. For us nature guys, people look at all your artsy nature shots from creative angles , and then buy wildlife or a sunset. Anything you can do to improve those sunsets is a good thing, and as far as I can tell DxO ratings are actually good for that.
You've told me, several times, real loud , you need a full frame. :D
APS-c just doesn't do it for you. :D

DxO's focus is low light performance, so much so, that they compromise their overall ratings for good light shooters by placing so much weight not them, and that's usually a bad thing, unless what you're interested in is DR and low light. Everything has it's uses, even DxO.
DR and low light is one area where I will see what they have to say.
But, if it's a stop better than a D810, I'll be happy. That would put it up in 645z territory.
Unlike you, I'm looking for a complimentary system, a system I can put in my camera bag to extend my K-3 system. SO I want this camera to be really good at the things the k-3 doesn't do well. The things the K-3 does well, (magnification for wildlife and macro, and frame rate) I'm happy with already.
I know a lot of people go poo poo when I say I miss the DR loss from the K-5 to the K-3... but for me it's just a fact of life, I miss it, and i want it back. Sounds like the K-1 might give it back tome and then add some extra, just for good measure.
The only reason DxO is of interest, is because as far as I can tell, Pentax didn't list the Dynamic Range on the spec sheet. Weird since the DR is listed on both the K-3 and K-5 spec sheets. If Pentax won't tell me, DxO will.

Short answer, yes you do.
Long answer
Obvious question, do you understand what dynamic range is? Dynamic range is how many EV the camera is capable of capturing. It is an input metric. jpeg is an output file type.
The adage garbage in, garbage out applies. In this case, low dynamic range input, in many landscape situations means garbage in. Jpeg is not some super function that equalizes sensors among all cameras and means a cheap point and shoot can match images with any camera that has more dynamic range.
The jpegs from my K-5 are better than the jpegs from my K20D which are better than the images from my Optio 90W, in many situations because the K-5 sensor captures more DR than the K20D, which captures more DR than the Optio 90W. Shooting jpeg does not get you out of benefitting from the best sensor possible.

For landscape.
What is the dynamic range... that is going to have a huge impact on it's DxO rating....
And low light performance. How do the noise reduction algorithms perform at low light? Ditto with the DxO ratings.
I'd still be working with a K20D if it weren't for those two functions, for landscape, the rest I can live with happily.
