Dead pixels or bleeding on S21+ after Jan 26 upgrade

[akadis1]

A few hours after yesterday's upgrade, my mostly new (6 months) S21+ started having display/screen issues.

I have googled this but found nothing similar.  There appears to be a repetitive shape (puzzle like) on the phone that makes things super hard to read, and there is something like green, black and purple bleeding.  Photos attached.

Has anyone seen anything like this?  

I have filed a repair service ticket since the phone is still under warranty, but since I am abroad it will be a pain to get it fixed. 

My next step before mailing the phone to the US for repair, is to do a factory reset as recommended by tech support.

But I am just wondering if anyone has had a similar issue and if it can be repaired easily.

Hi, We suggest you to get the phone examined by the authorized service technician to determine the root cause of the issue.

It would seem that the device was purchased in the United States, not clear if they are in Canada themselves now, or elsewhere.
