A bunch of things going on. First of all, the thumbnail you see on the camera is not the raw data, but the embedded preview jpeg which is processed according to the jpeg settings in-camera. You know, jpeg mode (bright, vibrant, landscape, portrait, etc.), contrast and sharpness, NR, chromatic aberration correction, distortion correction, shadow and highlight correction, vignetting correction and diffraction correction (not all cameras have all of these, but I think K-3 does). If these are enabled, they will be applied to the thumbnail.
When you import this into LR, it will first show the preview jpeg, then it will load the raw data and show you the much less attractive raw data. You see, raw data interpreted into an image is "ugly", it must be processed, developed. In jpeg mode, the camera does that for you. But the raw needs to be edited by yourself (or auto mode, presets, and so on)
That being said, color profiles are important, especially when it comes to orange and red colours. Instead of Adobe standard, I prefer to use Embedded or the Rawstudio colour profile (not sure if one for your version of LR and camera is freely available, but try googling for it), especially when there is a lot of red in the frame (flowers). The colour profile is the base, but it will still not looks as pretty as a jpeg or the preview jpeg.
I think SilkyPix, the raw software that comes with Pentax cameras, lets you apply all those in-camera settings to your raw photos. Lightroom doesn't have these presets, but you can download some nice ones to get the most out of those raw photos. LR has this great feature that lets you create a custom preset that gets applied to a photo as soon as you import it. I have things like Color profile, Noise reduction, and sharpening fixed this way, so I don't have to do all of this stuff for every separate photo. You can go all out and apply auto corrections, custom curves, added saturation and so on. Good luck
Edit: Oh, the above reply reminded me of color space. This is another separate thing, which sets the amount of possible colours that the photo can find. When converting between these profiles, errors can show up. This is why it is best to have the in-camera Colour space and the colour space of the developing software and the final jpeg photo all be in the same space. The internet works with sRGB, so most people use sRGB throughout their process. But some photographers use AdobeRGB (allows more "green" nuances) or ProRGB, since they allow slightly more shades of colours. But the snag here is that most people won't notice this anyway, and most displays/monitors cannot show such nuances either. Just avoid converting between colour spaces and you should be okay.
