Yes I do! But what’s surprising is how big the difference is when doing 2000->5000 verses 8000->11000. The 2000->5000 makes a big difference whereas the 8000->11000 results in very minimal change.
I’m very unsure about any of this right now. All of the metadata from my camera which looks, to me, like it involves WB & CT for a shot that I’m experimenting with follows:

The elements you referenced are included. However, in my mind what I’m looking for is what I’d call “As Developed”. In that, it seems to me that “As Developed” would be a property of the camera developed image. I’m not trying to quarrel about the terminology but if there is anything there that means as developed then I haven’t been able to figure it out.
That idea is pretty straightforward when working with 1 slider. But when it becomes 2 sliders what could be thought of as a discrete set of choices starts to look like an infinite number of choices. I’m pretty new to this business but I’ve been using a Windows computer and that has lead me to be experimenting with both GIMP and Rawtherapee (RT) as well as the Canon supplied software called Digital Photo Professional (DPP). Interestingly RT defaults to 6490 (pretty close to GIMP’s 6500) when editing standard format image type of files (i.e., non-raw file) with no ability to set an original temperature.
I think what I’m trying to do is learn how to edit digital images. I actually started by wanting to digitize our collection of family photos which brought me to GIMP and some pretty amazing results. This brought about some curiosity for editing certain JPG files also from the family collection. When I noticed how much latitude existed between what could be produced in a so-called digital darkroom verses accepting what cameras produced I became interested in taking pictures which for me, so far, primarily means landscapes and wildlife which present some opportunity for a former geek to try his hand at something that might have an artistic bent to it. This created the need to obtain some equipment capable of producing raw files that I can develop. Even though GIMP doesn’t handle raw files it still does some things that I like which aren’t possible with the photo centric software such as RT & DPP.
So raw is good but you cannot get away from the need to edit images that have already been developed.
When I came up with my question it seemed like something that ought to be a bit more straightforward than it is turning out to be. Even if there is an answer for how to do it with my camera that is no help for the mountains of image files I’ve acquired from elsewhere.
It sort of looks to me like there is no magic answer that can be applied to any, or even a good variety of, standard format image files (e.g., JPG, TIFF, etc.).
