Night light off after screen wakes from sleep

I have the issue that night light is always off when my screen comes back from a (blank) screen saver or the PC wakes from sleep. This has been mentioned several times but the recommended solutions do no address this issue but the issue that night light is not working at all. So to clarify, night light is working, it is just off when the screen comes back from screen saver. If I then check the night light setting, it is enabled and the slider is in the correct position but I need to briefly click on the slider for the feature to actually come on again. This is rather annoying as I often work at night and need to do this several times a day then.

Is there a solution for this? And again, please do not post any links on "how to fix night light not working" because it is working. It is simply off after waking from screen saver.

BTW I am on an HP ZBOOK 15 G2 laptop with NVIDIA Quadro 1100M and Intel HD 4600 (which Windows has stopped with Code 43 - I tried many things including the usual driver roll-back/update/removing hardware and letting it autodetect again etc, but have not been able to resolved it, so I assume that the system uses the NVIDIA card only - on the latest drivers). I run WIN 10 Pro, ver 2004 and am using an external monitor AOC Q3277.

Thank you.

    My issue relates to Windows directly and only - it is reproduced on different PCs.

    I thought I was alone here, I am having the exact same issues with you guys.

    Currently using an desktop and experiencing the issues with the night light turning off "but in setting it is toggled ON" when the monitor goes to sleep then wakes up.

    Windows 10 Home, Version 2004, OS Build 19041.630

    One other interesting characteristic that I noticed that were either missing or removed in the recent Windows 10 update (or as of a year ago or longer) is the monitor no longer "smoothly" fade to black to enter sleep mode. It just goes straight black, then I proceed to wake up the computer. Night mode is toggled ON but visually turned off.

    I had to go to setting to toggle the nightmode to "OFF" then the entire screen glitches from the color temperature it was in Night Mode to Off. Then I toggle the nightmode back on to enable the nightmode warm temperature.

    Example:

    Wakes Up Computer Monitor > Nightmode Broken - Color Temperature defaults to 6500K > Toggle Nightmode to OFF - Color Temperature Glitches instantly to 4000K and gradually goes to 6500K > Toggle Nightmode to ON - Color Temperature goes from 6500K to 4000K.

    I had to do this 50% of the time when I wake up my computer. It usually happen when the monitor turns off and I instantly tries to wake it up.

    This tells me Windows 10's setting is somehow not properly restoring nightlight setting when it wakes up from sleep.

    This had been an issue with me for over a year, just never bothered to speak up until now.

    if you haven't tried seeing if there's an updated graphics driver from the manufacturer of the graphics card (as opposed to say the manufacturer of your computer), try installing that first. see if that works for you.

    This is not a driver issue: my laptop is AMD oem driver powered but my PC uses Nvidia with their newest native driver. And both devices wake up without normal colors temperature but Night Light mode's button on if a user was logged in during sleeping time.

    It would be nice to know where to write to MS they start fixing this - this is not a free software to suffer such a thing...

    some people were able to fix it that way, so I thought I would suggest this to this person just to check.

    as you know I've tried various fixes. what I've learned at this point is that it doesn't matter if you use sleep, hibernate, or hibernate plus sleep the problem for me remains. I've run dism, sfc, set power options to default, run power options troubleshooter, changed to drivers, updated drivers, nothing helps. But since the problem only arises after the computer comes back from hibernate or sleep after a few times, I am pretty secure in saying that the problem lies just there, something gets corrupted when going into or coming out of sleep or hibernate mode in pc settings. since it works fine after booting and after the first or second or sometimes even third return from sleep/hibernate, it's not a problem with pc settings itself. 

    if this is indeed the root of the problem, I'm not sure what to do to fix it other than roll back to 1904. which I don't want to mess with. at this point, I've given up trying to find a fix and will hopefully wait for someone at microsoft to see this and fix it. I don't know what else to do.
