LTO technology is backwards compatible two generations from 1 to 7 and one gen on LTO-8, so an LTO-8 drive should be able to read and write LTO-7. https://www.lto.org/technology/lto-generation-8/

I'm not sure why you would like to label an LTO-7 as LTO-8 tape (will most likely cause trouble) but you can do so by using an LTO-8 barcode tag (last element in the barcode tag is used to define the LTO generation, so L8 whould do the trick) I create the ones I use here: https://tapelabel.de/

No idea how LTOs work, AITs would throw a "premature EOT" when you used
e.g. AIT-2 tape in AIT-3 drive. That wasn't a problem when reading, but
writing to an old-version tape could potentially mess up your entire volume.

That's when it does matter what the native medium capacity is.
