Lightroom colour profiles: Pentax SLR Talk Forum: Digital Photography Review A recent discussion on color profiles.
Pentax has traditionally had a problem with reds bleeding to magenta. They are not the only ones however. The red channel always clips first.
The RAW files are effected by the image processor. The Sony A900 and the Nikon D3x both had the same sensor, but different color profiles because they had different image processors. Sony used a heavier RGB filter than Nikon which gave the Sony better color, but the darker filter hurt high ISO performance and that is where the Nikon had the advantage. Everyone criticized the A900 for poor high ISO, but the colors were excellent at lower ISO making it a great studio camera.
Every RAW processor is using a different logarithm to process RAW files and they will all give you slightly different colors. Lightroom is the easiest to work with. I think Capture One gives you the most control and best colors, but I prefer DxO for a lot of my work. The Adobe Standard Color profile for the Pentax K-3 is not very good. The in-camera RAW processor produces better colors than the Adobe Standard Profile assuming you nail WB and exposure. The Embedded profile is better, but an X-Rite custom color profile is the way to go if can.

LR is assuming you are going to print the image and you need to increase brightness for prints. The illuminated screen will always be brighter than the reflective print.
