When I plug my external monitor into my laptop over using a USB C/Thunderbolt to HDMI adapter the colors are washed out. When I'm plugged the built-in HDMI port everything is fine. This doesn't affect the built-in display.
The major difference between the two configurations appears to be that when I use the built-in port the Nvidia graphics card drives the display, but when I'm running over Thunderbolt the onboard Intel graphics chip is driving the display.
Now, the really crazy part is that if I open up the Intel Graphics Settings > Display > General Settings and I change any option then immediately hit Cancel it fixes the colors. The next time I reconnect the display or reboot the machine colors will be washed out again.
I took a quick video with my phone. It's super fuzzy, but you can see that I change the scaling setting from Maintain Display Scaling to Maintain Aspect Ratio, then just click Cancel. The display gets noticeably darker as the colors get fixed.

I've updated both Intel and Nvidia graphics drivers (24.20.100.6025 and 397.64 respectively). Tried a different Thunderbolt adapter. Tried playing with the color range in the Intel settings. I've also noticed the Video settings seem to do nothing, so the color range settings probably aren't even taking effect.
I suspect there's a bug in the Intel driver.
Laptop: Razer Blade 14" (Late 2017)

I've also attached graphics information from the Intel Graphics Settings.

Possibly related:
Seems there's a bug in recent driver versions where displays over USB-C are not recognized properly.
EDIT: Driver version 21.20.16.4678 indeed fixes the washed out colors. It didn't add the missing options under General Settings, but it's a step up.

Yeah, same here! My USB C monitor now matches the colors on the HDMI monitor with the 4678 driver!
As you also mentioned, the option to enable full quantization range is missing on the USB-C connected monitor, but it seems it is applying it.
Sidenote: How do you prevent window from auto-updating the driver?

I haven't done anything to prevent it. It hasn't auto-updated so far. I'm actually not sure if I've ever noticed it auto-updating my Intel graphics driver. It was slightly out of date when before I updated to the newest then rolled back to the slightly-less-broken version.

I have the same problem when using usb-c to hdmi cable. Rolling back to 4678 driver fixed the problem, but obviously i would want use latest drivers. On latest drivers changing ycbcr off-on-off fixes the problem temporarily for couple of seconds but it reverts back to poor after that, (washed out, banding on color band test.)

Same problem when external Dell monitor is connected to my laptop via USB C to HDMI adapter.
When I'm plugged the built-in HDMI port everything is fine as well.
The workaround on Intel Graphics Settings > Display > General Settings works.
When I rolled back to my previous driver version, the problem existed and persisted (no fix) when I tried the workaround
Just to note that I have a xiaomi laptop and when I try to install general drivers from intel for integrated 620 graphics card, I
get an error that drivers are controlled by manufacturer (or something similar)
Any news about this issue?

Temporary solution (till next login or boot) is:
Go to Graphics Control Panel > Display. Then, for instance, change the value of the Refresh rate or Resolution. Don't apply but choose Cancel. Et voila! The full range of colors is there. Strange...
BTW Choosing the Full range option in the Video section does not fix it.

Oh, wow, worked! I was sceptic but after hitting cancel the colors kicked in. Super trick 😉

It's 2021 and this still works hahaha. I've been banging my head on my desk for two days 😂. My PC would sometimes boot with the right colors or with the washed out one like a lottery.
This truly fixed it: "Go to Graphics Control Panel > Display. Then, for instance, change the value of the Refresh rate or Resolution. Don't apply but choose Cancel. Et voila! The full range of colors is there. "
While this worked for me once: "BTW Choosing the Full range option in the Video section does not fix it."
Thank you so much.
