Maximising exposure sensor = what exactly ??

Maximizing exposure - the lowest SS that won't cause motion blur issues along with the maximum aperture that won't cause DOF/sharpness issues.

What I do with the XH2 in dim light is having EV +2/3 to 1. Is it ETTR or maximization of sensor exposure ??

In low light, by shooting at EV +2/3 to 1 stop, you are most likely increasing the ISO, not the exposure (not ETTR). In doing so, you are limiting the highlight headroom and not improving the noise significantly (noise is primarily an exposure thing or rather, the lack thereof). In the ISO invariant range of the sensor (usually around ISO 1600+) there is no advantage to setting at high ISO in-camera vs. pushing the brightness in post. See response to JNR below.

OTH I am not sure as well that the 40 mpx sensor is as ISO invariant as the 26 mpx is ??

I've seen no evidence to suggest this.
