Should I really be concerned about this?

I made a thread about a week ago about how my school is forcing all juniors to take the new SAT but I don’t want to since my old SAT score is high. The general consensus on that thread was to take the test and cancel my score immediately afterwards, which I plan to do (unless I feel very confident I can pull off a 1500+).

However, someone’s reply worried me. They said that if I cancel my scores, many universities that require all scores will be suspicious and think that I’m withholding all my scores because they know March 2 is a popular in-school SAT day. Is this a legitimate concern I should have?
