The burn-in protection on Venu2(s) devices with CIQ4 falsely triggers and turns off the display

I have ported several watch faces with Venu1 AOD support to the Venu2 and Venu2s devices.

My AOD modes are straight forward. I'm using a dense pattern clearing every 2nd pixel row or column on the screen alternating each minute starting with the first row/column or the second row/column.

This ensures that less than 10% of the pixels are on and no particular pixel is on for more than 1 minute.

On the Venu2 the simulator detects a screen burn-in. On the Screen Burn-In Simulation window it looks like the overlay pattern is ignored.

Also some drawing artifacts are missing on the burn-in screen for example the minute and hour hands.

I'm in contact with 2 other developers who have similar problems with at least some of their watch faces.

I already uploaded my watch faces with Venu2 support to the Connect IQ store and received feedback from a user who also owns a Venu1 that

the AOD is not working on his new Venu2. - It turns off the screen.

So this is potentially not only a problem of the simulator but also of the actual device.

Here is a screen recording of the problem in action highlighting the differences between Venu1 and Venu2:
