In LR, you can change to match the camera modes if you wish, including Faithful, ....
Everyone does see Reality differently, and I find that none of the software can reproduce a image colors and lighting and saturation exactly as I see them. Thats why there are different competing tools, if they were identical we would only need one.
If DPP works that well for you, then you may not need LR if you are that dissatisfied with the results. Perhaps you only need one...
I used only dpp for about a year and when I switched I found that loading into LR did seem to change the images a bit more than I felt dpp did. I ended up taking many, many tutorials and webinars about LR and quickly learned that I could create my own presets for when photos are uploaded into the program.
I've got several custom presets set up and I use them for different scenarios... for instance, if I shoot a wedding, I use a preset I call "Ken's wedding preset", it applys my settings to the raw images as they come in. It's simple settings, for instance set to Faithful, Temp set to 5400, lens corrections on, things like that. No, all the images that come in don't come in exactly the way I want necessarily, but they are close for most of them and I make minor adjustments from there.
I do the same thing for wildlife shots, portraits, landscapes, etc. Try learning how to use the presets before uploading your images and you may find a whole new world of possibilities! Who knows? I just think since you've spent the money on it, you should try to exploit it to the best of your abilities... we can't all be wrong! Or can we??
