You're right, it's not changing the DNG files, not even Adobe Camera Raw.
The camera records an XMP sidecar (or something like that, it's just an XML file containing some metadata about the DNG files) alongside the DNGs, and ALL camera raw software reads that, usually by default applying it. So if your sidecar file says you shot it with a color temperature of 6500 Kelvin, the raw decoder will apply a color balance setting for 6500 Kelvin, until you override it.
The preview image that ACR generates might actually be embedded into the DNG file though, I'm not certain; either way, the raw data remains untouched. It might alter the sidecar file with the settings it used when de-Bayering the image, but that still doesn't change the raw data.
Even in Resolve, the default behavior is to apply a rec 709 LUT to the raw footage unless you override it, which means that you're getting a teaser view of what it might look like if you amp the contrast and saturation up. Once I discovered the BMDFILM option though, well... wow.
