Is anyone using Dell PremierColor with the XPS 15 9550 having any success with it?

Long story short: I find it utterly unusable, and the system seems to be better off without it.

Encountered problems since I unpacked the laptop, somewhat in order:

1. Clicking the tray icon from Dell PremierColor did not launch the application at all. It didn't do anything (the Dell Update application still seems to suffer from the same symptoms). Seemingly when it did eventually pop up (we are talking after several minutes here), the brightness seemed to go down to unreadable levels. First few usages I remember having to reboot the system since I seemed to be unable to move the brightness up again, it just kept dimming and dimming every x time (I presume it had to do with premiercolor, but not sure).
2. I updated all stuff on the laptop, after which at least PremierColor seemed to launch now.  However, I do not understand how the settings from PremierColor interplay with those from the Intel Graphics settings.
3. I don't have a clue how settings are saved per profile in PremierColor, they seemingly are not. Switching between profiles repeatedly seemingly keeps setting the brightness values to other levels (lower and lower?). What is the purpose of this?
4. I wanted to watch Netflix for the first time on this new computer just now, and the colors were totally *** (looks like horrible encoding, blocks of incorrect colors). However, given the 'fun' history with PremierColor thus far, I simply shut it down, reloaded my calibrated profile settings from the Intel Graphics options, and all colors are fine now.

What does all of this mean? Do I have faulty hardware? Is the software totally useless? Can I now no longer benefit from Adobe RGB colors (which I might have to rely on in the future?).

P.s. Just for context, problems with this laptop so far (I am seriously getting aggravated with this laptop):

1. Brightness flickering due to BIOS update, which is now rolled back, somewhat improving the issue but it simply occurs less.
2. Broken battery (battery light indicator started flashing after +- one week of usage)
3. Overall sloppy Windows 10 window manager performance from the Intel Graphics 530 card, where it can't even smoothly render maximize window animations.
4. Problems with the prepackaged sofware (dell update does not launch, premiercolor issues listed above)
5. Just recently noticed scrolling in windows with treeview elements in it is entirely unusable and lags.

All of this with an out-of-the-box installation. This product for the past week has been nothing but a waste of time (including >2 hours on the line with Dell support just to establish what I already told them in the first 5 minutes). For anyone considering buying this, wait until all this *** is fixed.
