It does for a lot of people...myself included. Not 100% of the people but the majority.
I wasn't going to mention it just in case you weren't one of the lucky ones. Didn't want to jinx you.

And yeah, it is essentially silent. I have to put my ear right on the machine to even hear the motor noise.
You've been used to 10 cm and the drop to 8 wasn't comfortable. I should have anticipated that. I experienced similar sensations when I was experimenting and worked up to 13 cm for a week and then made a sudden drop back to 10 (long ago on my first Respironics APAP).
The for Her model has a second apap mode with a different algorithm. Target marketed for women and "more attuned to women's breathing" but I think that is just a marketing ploy to give us women a reason to think that someone actually wants to do something special besides a pink color or flowers.

So you have cpap mode, regular apap mode and the for her mode. Like 3 machines in one.
The for her algorithm is more designed to address flow limitations a little more aggressively. When I compared the flow limitation graphs in both modes the for her mode showed the FL graph as being a lot more active than the other apap mode. It's more sensitive in that regard. The increases in pressure might be a bit more gentle and if you have 2 OAs within a minute the machine establishes a new minimum so that it doesn't happen again. I have had that happen a few times.
I have used both algorithms just to test them out. I am currently using the for Her mode. It's working out well and I just never had a reason to want to go back to the regular mode.
There is no reason in the world that I can think of that the male of the species might also find this algorithm useful in some situations.
Is it absolutely critical...of course not but if the cost is the same get that special algorithm just in case you might like it and sleep better with it. It's just another tool to have in our tool belt to maybe help us out if maybe needed.
If the leaves bug a guy...for 20 bucks you can get a black or plain gray/silver face plate and it's easy to change out. I did it for a guy who just didn't want the leaves. BTW he loves the machine too. Says its worlds better than his PR S1 APAP....and silent too.
My own macho hubby ....he says he doesn't see the big deal...it's leaves and not flowers and he wouldn't be bothered by the leaves.
You can read up a bit about that extra mode in the clinical manual but it doesn't really explain it in much detail.
You may or may not need or like that extra mode but at least it would be available in your quest to improve your sleep quality.
We use all the tools available whenever we can.
