The 2’s, 7’s, and 8’s, as well as the letters B, C, D, and L are all 5 dots wide. The 1 is only 3 wide, and the 0 is only 4 wide, but each seems to have a larger gap to the next number. The punctuation (colon and period) seems to be 2 dots wide with significant spacing around them. That suggests this font is a monospaced font with each character 5 dots wide, spaced 2 dots apart.
So it makes sense for 3 to use all 5 dots of width. And the one unambiguous 3 we see is 4 dots wide, placed in a spot approximately one dot too far right. The way you’ve filled in the 3 makes the most sense, and leads to the straightforward conclusion that the unidentified character is a 3.
I think you’re right.
