Tell that to my wife whom had one of those and it was a lemon and had to be bought back, so she isn't sure it is any better than a Tesla. For sure there are lots of very happy S class owners out there. She is not one of them and never wants another one.
Honestly I've never heard of anyone else with a yellow IC border, just the main touchscreen.
/edit. again this is only visible under direct sunlight. You can't see any orange under normal operating conditions. It really doesn't bother me at all.
I have this on my April 2019 build and it became visible within the first 6 months of ownership. I also have the center screen yellowing, which became visible within a few months.
Is the IC display panel behind the bezel not rectangular?
If so, the yellow boarder here is following the plastic moulding and not the screen edge. The edge is hardly getting more sun exposure than the centre area, so it is / is it more likely to be the heat of the plastic surround.
I haven't followed other yellow boarder threads too closely, so heat may already be known as the main cause, but that has me thinking about keeping plastic surface temperatures down where possible.

The yellow border is more difficult to see on the IC because of the dark background, but can be seen especially in indirect sunlight. I have the IC yellow border, but have not fixed it yet because it is not too noticeable. I am thinking about treating it by creating a new UV box for it so I can reuse the UV LED bulb from my DIY MCU fix.
I thought I had my MCU screen completely cured, but as the weather in the Sacramento area has started to get warmer, the yellow band has slightly reappeared so I will be doing some additional curing on that too.
I was following the earlier posts on this and the curing of the adhesive and also followed some links about the process in general.
What I didn't really understand was what is happening to the adhesive (presumably accelerated by heat) that in general effects the boarder of the screens more / sooner than the middle. I would expect the IC to heat up more all over as it gets cooked if the sun is shining on the top of its housing.
I wonder if anyone has taken thermal images of the screens and surrounding surfaces.
And, for the issue to still be plaguing new vehicles makes me think it isn't a manufacturing issue as much as a design issue using displays or assembly processes / materials that aren't up to the environmental conditions inside the cabin.
If it really is some form of under-exposure in manufacturing, why hasn't that been addressed? Is the yellowing an acceleration of aging? Often uv exposure also accelerates aging of plastics, so is it reversing something in the case of screens yellowing, or just masking it?

I'm pretty certain there is a fix for the IC yellow border. A friend of mine had his fixed (same curing method as for main screen) at Rocklin, CA service center.
When I was researching the issue to create a DIY curing solution, I found out that the LOCA can include additives for avoiding discoloration, but it costs more. There may other reasons why Tesla uses the particular LOCA they do, I don’t know. I also read that thicker applications can lead to partial curing and heat can cause the deeper layers of LOCA to discolor even after top layers were previously cured. They use LOCA to seal the screen and provide a solid, clear bond. I have done my curing incrementally because I don’t know how much is too much and don’t want to take a chance of over doing it and causing damage. I also completely mask off trim and other non-screen material when curing inside the box I constructed. Since UV at 365nm can damage eyesight, I also made sure my box is sealed tight to the screen using plenty of painters tape. I cure in a dark garage for cooler temps and to check for UV light leakage.
And EVERY SINGLE EV AUDI AND PORSCHE SOLD GIVES THEM MORE CREDITS TO SELL that many more GHG-DUMPING ICE AUDI AND PORSCHE cars and SUV's.
Yeah, that's smart . . . not.

BTW, as an additional data point, both of our 2017 MS's had the yellow border on the edges of the MCU. Both were repaired with a short, 2-hour visit to the Dallas SC.
No muss, no fuss.
Could Tesla have handled this better? Of course. Poor communication, delays, questionable customer service, etc. all left some, like the OP, with a bad experience.
But Tesla did, eventually, implement a wide-spread program to fix the bad MCU's.
Now we have 2019 and 2020 MS's; no MCU screen issues yet, or likely ever.
Planet's future? Ever so slightly better because we've added two more MS's to the world's ground transportation fleet, and sent some money Tesla's way so they can continue to grow and hopefully save our only planet's future.
When you look at the BIG PICTURE, sometimes you get a better view of what is really important . . . .

Yellow border: much disinformation or obsolete information in this thread.
Remember that old TV show where the the detective says: "only the facts, ma'am"?
The facts:
I used the app to set up a "yellow border on screen" appointment.
Delivered the car to Service Center at 10:18 am.
Red box with UV lights and cooling fans was placed against main screen.
Played with the new vehicles, had a nice lunch at a nearby restaurant.
UV treatment finished, drove 42 miles back home, started charging at 2:09.
Yellow border gone, no fee. Friendly staff, pleasant experience. No drama.
