If the processed image (not RAW) is over-exposed, it is clipped. There is no more data that will come forward if you pull the levels down. Some times careful grading in Resolve can make a blown out house wall look better by isolating whatever contrasty elements there are and tinting the remaining white areas slightly warmer. This is mainly a go-to with log footage from 10 bit sources, as the Mavic is just 8 bit you need to be careful when pulling the colors too much as banding will occour pretty fast. A blown out white sky can't be brought back, but a skilled colorist may paint it to look allright.
When I fly I expose and plan my angles for my subject, be it landscape, house, people or whatever. Often the sun itself will clip, so there is just a matter of deciding how big of a bright spot you want in your footage - traded for some more latitude in the shadows and mid tones. In general I leave just the edges of clouds in the highlights (use exposure warning and histogram), because clouds that are clipped half way in looks really bad in my opinion.
