The display of my 2019 MacBook Pro 13" (2 TB ports) shows color glitches when connecting to my iPad via Sidecar and while TrueTone or Night Shift are on. Specifically, the shaded areas around windows appear glitched and the whites appear not color-matching with the current temperature set by TrueTone/Night Shift.

Yep, the same issue here as well, it's a big glitch and is only avoidable when True Tone is turned off. Turning off True Tone and turning it back on while Sidecar is in function will sometimes help but usually not, hope this will be fixed in a future update.

I have the same issue over here. What iPad are you guys using? I get this issue when using an iPad 6'th gen. And as Mzdaspd mentions, I need to turn off True Tone before whites are displayed correctly
@kevenxixi the problem only exists when sidecar is in use, otherwise, when I am just using my 2019 MBP 2TB by itself, the image quality is just fine. It may have to do with the sensors within the MacBook fighting with the sensors in the iPad. This is just my thought though.
I'm also having this issue.
I've yet to get wireless sidecar working but when wired with True Tone enabled the shadows around windows are "glitched".
I figured out this is only the case when using the built-in Intel UHD Graphics 630 GPU, if the Radeon Pro 560X GPU is active then True Tone functions as expected. Would seem to suggest that there is an issue with the built-in Intel driver and Side Car.
What "fixed" it for myself was to open display settings in system preferences and within arrangement, move the top white menu bar over to the mac display vs the iPad display.

Oddly, switching to Radeon graphics card works for me as well. But once I switch back to Intel UHD, the glitches are back. I guess I will have to use the more power consuming Vega card when I use Sidecar, until they fix the bug.
And the problem occurs for me on Intel Graphics card when either True Tone or Night Shift is enabled.
Turning off Automatic Graphics Switching is no option for those with no dual graphics. So that's not a fix.
But yes, the problem seems to be related to the Intel driver and its connection to TrueTone/Night Shift and Sidecar.
All of you send feedback to the Catalina product team. Be specific about operating system versions, Mac and iPad models, and settings on the Mac that create, and if possible, eliminate the issue.
I reseted the PRAM (https://support.apple.com/en-us/HT204063) and now it seems better. Did you try that?
This issue has not been fixed with today's update 19A602
I’m using the 11” iPad Pro. This is my issue:
I am having the same issues. I have to turn off True Tone in order to get it to display correctly. Hopefully this gets corrected soon.

They don't give you the option to select Mac OS Catalina 10.15, highest version is 10.14.6 so this will not help.
I don't think that's a mandatory field so I left that blank and used the title to indicate that it was a Catalina issue.
