Improved high-ISO M43 performance available now?

No, this post is not about any new M43 camera or any new sensor.

Instead it's to point out that there is a new version of DXO photolab available (version 4), with a new level of noise reduction they are calling "DeepPRIME".

Here's a video from PhotoJoseph about the new DXO version - the part about the new noise reduction begins at around the 8-minute mark, and shows examples of photos taken with a GX8 at 25,600ISO and a GX85 at 16,000ISO. Bear in mind it is explicitly a promotional video, not an impartial review.

Given that DXO Prime was previously around the best noise reduction software available, if the new version does turn out to be noticeably improved, then it provides a path to improved high-ISO performance.

It also introduces an interesting (for me) philosophical question. A number of people recently have been complaining about the lack of a new M43 sensor with improved low-light performance. Let's say, for the sake of argument (and knowing this forum there will certainly be argument), that the improved "DeepPRIME" feature improves the high-ISO performance by around a stop, bringing the performance of current M43 cameras up to that of current APS-C cameras (used without "DeepPRIME"). For those who have been tempted to move up a sensor size purely for improved low light performance, would that improvement remove the temptation to change systems for that reason? Or, given that similar improvements will also be available to larger sensor sizes**, is the temptation still there? (i.e. Is there a point at which you say OK the low-noise performance is good enough now not to be an issue, or is it a continuous chase after something better?).

(** This may not apply to Fuji X-trans sensors, as I don't believe DXO currently supports them - not sure if this has changed in the new version).
