Relative resolution is directly related to the ratio of number of pixels to image frame size. However, I agree that better light sensitivity is a function of pixel size alone.
I think you're having a hard time grasping whats going on here. You seem to be implying that the because the pixels are larger, they are capturing a larger area of the frame, and thus have less resolution. This would be the case if the the sensor size remained the same, and thus, the pixel count went down. In this case, the sensor size is increased, the pixel count is increased by 15%, and thus the resolution is increased by the same amount. As the lenses have been correspondingly adjusted to reflect the new sensor size, the camera placed at the same spot will have similar angle of view on the X7/x5s, and the resolution of that similar captured image will be higher in theory (DJI's use of a stronger OLPF and more aggressive Noise Reduction on the X7, appears to be making any resolution increase a wash at this point, but that's another, much more complicated, matter).
