Fujifilm X-Trans matrix and raw converters
DNG raw can be two types: "mosaic" and "linear". The mosaic DNG is a common raw as is. The linear DNG means that color interpolation already processed by the DNG converter. It's suitable, for instance, for raw converters which don't understand a non-standard color pattern.
Adobe DNG Converter has several parameters for conversion responsible for compatibility with other programs. They can be set at once as preset, for instance "Camera Raw 7.1 or higher compatible". Or can be set explicitly: version of DNG specification (1.4, 1.3 or 1.1), linear or mosaic, compressed or without compression. Let's see how this parameters changes the size of the DNG file.
|Mode\Photo||extreme||ISO 200||ISO 6400|
|RAF size||25 MB||25||25|
|Camera Raw 2.4||48||54||54|
|Camera Raw 4.1||48||54||54|
|Camera Raw 4.6||48||54||54|
|Camera Raw 5.4||48||54||54|
|Camera Raw 6.6||48||54||54|
|Camera Raw 7.1||16||20||18|
As you can see Adobe DNG Converter creates mosaic DNG only in the mode "Camera Raw 7.1 or higher compatible" and linear DNG with roughly 3 times more size for the other compatibility modes.

As you can see the proprietary RAF format much better supported, than open standard DNG. Thus don't use DNG if you don't need it.
|ACDSee Pro + mosaic DNG||ACDSee Pro + linear DNG|
|dcraw -a + mosaic DNG||dcraw -a + linear DNG|
|Raw Therapee + mosaic DNG||Raw Therapee + linear DNG|
|Captire One + mosaic DNG||Capture One + RAF (for comparison)|
As you can see sometimes DNG can be useful. For instance, if you prefer ACDSee Pro or free Raw Therapee.
Only Capture One shows accurate result comparable to the camera jpeg. And it has the promising auto correction tool. Also I was surprised by power of Dcraw, but this program is inconvenient for serious work.
