We see very similar color break and texture weirdness pretty often in seedlings, and to date, no confirmed viral infections,... Now that said, it's damn difficult to diagnose because the symptoms can look like other things. The only way to truly confirm viral infection is with a special test kit, basically a home ELISA test,... worse, these tests are very specific to the viral type, not covering any number of other possible viruses,....
Bottom line, it's very unlikely, so grow it out for now and see if other signs can confirm either way,...
