There are a lot of time issues here regarding timezone and date time discrepancies. I did not find one that addressed my issue:
Conditions:
SP Regional settings UTC -6
PC Set to Central Time
MS FLow populates date field with UTC()
Sharepoint reads correct local time
Powerapps shows the next day if date is posted in the afternoon-ish.
Setup:
MS Flow populates Engineering Released date with UTC()

Sharepoint list shows this, which is correct:

Powerapps view shows this... in both a datacard, and a lookup field (value wrong):

Lookup command:
"Release Date: "&Text(LookUp('Engineering Change Request',ECR_Number=ECRSelected,Engrg_x0020_Release_x0020_Date))
Settings for datacard:
Not sure how to fix this, without a "fake" that will still be correct when time changes for daylight savings.
Thank you.
