This seems to be the case. Thanks! I also found this website where we can see details regarding segwit trx's [link]https://blockchair.com

blockchain.info is not very segwit friendly.

<p>If it's a P2SH output and the redeem script is OP_TRUE then it's an anyone-can-spend and you don't have to provide anything in the scriptSig</p>

It's explained in the other answer, it has a witness.

It would help to see the raw transaction, then one could use „decoderawtransaction“ and analyze the details... at least on my iPad the imgur image seems to be blank... no hexcodes visible
