I agree. I've noticed in the past that games with Sony cameras usually look better than the LDK 6Ks, though I haven't really seen if the 8ks are better. I think some of the saturated look of the Sonys is the masking settings. Also the look set by the video operator can be a big factor too. Detail settings still seem to be set by subjective observation rather than objective measurement, and there still seems to be a significant number of those who love to add outlines, sometimes referred to as "Contour Kings".
One difference in 720p between the Sonys and the LDKs is that the latter uses sensor pixel grouping to essentially emulate a native 720p imager. Sonys create a 1080p image and then scales it to 720p. At least vertically that should allow better vertical detail depth of modulation. Both scale horizontally.

Is filtering is considered to be compression? Interlace mode with its typical sensor pixel row grouping also creates a filtering effect but I don't know if that's referred to as compression. Even the pixel element is averaging the detail in that area, though the optical low pass filter should reduce that to a minimum. There is also the RGB separation to emulate human color perception which could be considered spectral compression. Even the successive still images could be considered temporal sampling and a form of compression.
