38mm Sport is actually on the right. Though it's relative.
Yes, we're keeping them. It's really not noticeable in everyday use and we're not going to do image editing on them. Plus she uses Mickey face almost exclusively. Clipping is visible there, but it doesn't make the face look bad. My wife never noticed that before.
Also, I see the same as some previous poster - it's much less visible in day time compared to what I have seen last night.
I went into the store today to collect a SS WSB and went through pairing the watch with my phone etc, this unit was a week 24 and displays the same black clipping as the week 23 Sport I sent back.
I pointed out the issue when compared to the display units displaying the same Solar and Mickey Mouse faces and they could see what I meant.
It looks like they have changed the supplier for the screens and they are no longer being calibrated correctly for grey scale or colour.
I have decided to pass by this generation of apple watch due to this.
Good luck getting a decent screen guys.
