NFT image CDN inconsistencies within a collection

I've noticed an inconsistency whereby some tokens are missing both nft-cdn.alchemy.com and cloudinary links, and images are ipfs only.

Even within a single collection, some tokens include the CDNs, and some not, I've pasted an example below.

Is there anything an end user can do via the api to trigger Alchemy's servers to correct for this?

Also, if stuck with ipfs only, can one expect the performance of https://alchemy.mypinata.cloud/ would be faster than https://ipfs.io/ as a gateway, in general?

Example: "girlies-nft" = "0x4f7e2a72a99d45f4fd5a2fc211f8dc5c36a049bd"

"tokenId": "8",
...
"media": [
{
"raw": "ipfs://QmaBvtjsTC52cJLtccS5vg7odGqJ9pniBTGd7FiV2QPHwi/8.png",
"gateway": "https://ipfs.io/ipfs/QmaBvtjsTC52cJLtccS5vg7odGqJ9pniBTGd7FiV2QPHwi/8.png"
}
]

"tokenId": "7",
...
"media": [
{
"raw": "ipfs://QmaBvtjsTC52cJLtccS5vg7odGqJ9pniBTGd7FiV2QPHwi/7.png",
"gateway": "https://nft-cdn.alchemy.com/eth-mainnet/efcbabbec2d58642f969e6acdc6b736a",
"thumbnail": "https://res.cloudinary.com/alchemyapi/image/upload/thumbnail/eth-mainnet/efcbabbec2d58642f969e6acdc6b736a",
"format": "png",
"bytes": 2459511
}
]

And there are hundreds of tokens like #8 that are ipfs only.
