All bech32 is when decoding the QR code in upper case.

For presentation, lowercase is usually preferable, but inside QR codes uppercase SHOULD be used, as those permit the use of alphanumeric mode, which is 45% more compact than the normal byte mode.

I also mentioned this on the information section of the site (second paragraph).
