U4025QW, Apple OS, support issues

I own Dell u4025qw monitor and would like to report the following problems that I observed on macOS. I also provided references about similar issues reported by Windows users.

1. DDPM (or Dell driver) does not support volume control for the built in speakers in the u4025qw. The volume controls are "grayed out" and cannot be controlled from OS. The workaround that aIl found is to install commercial application like "BetterDisplay" that enables volume controls for Dell.

2. When Auto Color balance is enabled, sometimes the starts to change white balance very ~15-30 sec even so lightening setup is the same and there is no changes in the environment. The same issue is also reported by online reviewers - https://www.tomsguide.com/reviews/dell-ultrasharp-40-curved-thunderbolt-hub-monitor

3. Auto balance feature works a bit better but keep monitor very dark, even when you change the auto level to HIGH in ddpm

4. In general DDPM software is not stable and crashes or causing hangs. This is my second dell monitor in 2 years in for both monitor DDPM stability is poor.

5. The monitor does NOT support 120Hz freq for Apple devices based on M1 and M2 chips. Dell should disclose this limitation explicitly. This is limitation of M1/2 silicon. Nevertheless, external user already demonstrated how monitor refresh rate can be increased to 100/110hz using using custom EEID configuration here. Why Dell cannot enable this by default through their drivers ?
