Olympus implemented new advanced noise reduction, now in raw also

Olympus claim it’s a newly developed sensor and with lower noise, and both wider dynamic range and improved color discrimination at all ISOs it is one of the most significant upswings in performance we’ve seen in this format.

While the E-M1 Mk II sensor proved to be competitive in some aspects with the APS-C sensor in the D500, against the full-frame Nikon D750 it is unsurprisingly, still some way behind. From base to ISO400 the Nikon D750 sensor has only slightly wider DR than the D500, but that equates to a solid 1.5 stops at base over the E-M1 Mk II. Moreover, the full-frame sensor has far better color discrimination and lower noise than either: in our low light ISO test, there’s an improvement of around +1.25 EV over the E-M1 Mk II and D500.

Here's a pretty fair "hands-on" comparison of the E-M1 Mk II compared to the Fuji X-T2. Swings and roundabouts...take your pick.
