Thank you again. I didn't see anything in metadata but I checked a few settings I generally use with my G1 and they are set up pretty close to what I have setup in my D-Lux 4. I generally use Dynamic Color or Dynamic B&W for everything. I use Smooth B&W then PP for when I want a IR-like effect. I limit the Color Presets to ISO 800 on D-Lux 4 and 1600 on the G1 in good light. I limit the D-Lux 4 and G1 to ISO 1600 in B&W except for web-centric media in which I will let the G1 go to 3200 at times.
The G1/ D-Lux4 actually works out well for me for a good walkaround small combo system until a smaller Micro 4/3 is released. The menus are almost identical and the color reproduction is extremely close from both cameras. I often have to check the metadata to tell which image came from which camera which isn't a knock against the G1 but a compliment to the D-Lux 4/ LX3 RAW files.
I used this combo this weekend (and during a Napa trip last month) during the Rock and Walk Walkathon over the Memorial Day weekend in Sacramento. D -Lux 4 covered the wide stuff (24-60mm) and the G1 had the Lumix 45-200mm (90-400mm) on it. It worked out well for me although I didn't take as many longer shots as I thought I would. Everything was obviously handheld. There's more stuff I took in the Small Sensor section and my gallery for a direct look.
