Because the other comment had a ~~useless~~ counterproductive step in it, namely base64.

Maybe, but also I think I was looking at the raw 'data bits', not 'binary' data. It's actually almost exactly 4GiB, even when dropping down to minimum error correction (1.7 GiB otherwise).

(1454942×2953)÷1024÷1024÷1024≈4.00

Edit: So if alphanumeric mode could store lowercase letters, base64 would've stored more.
