DNG & RAW informations

Since the first management of RAW files supported in Denoise at the time, and now still in PhotoAI, I notice that the RAW files we put in, which have a certain amount of information, when processed and output as DNG, the DNGs do not have much more information than a TIFF, which is at the very least astonishing, since the RAW contained a lot of information, which is very inconvenient in the image processing chain. For example, when importing it as RAW into DxO to process the image, and modifying this information that we bring into Topaz and then into Photoshop, we are trapped. One must go, for example, through DxO, then through Photoshop, and finally through Topaz, all the while knowing that the output file will be much less editable than the RAW file is.
