Most likely that 800 Gb is compressed?

I'm saying that the quoted 800 Gb may only be valid with 2:1 compression, which depends on the data.

Looks like tape is 400Gb uncompressed, and 800Gb in compressed size...

While formatting the tape, it will ask you to specify medium size, you need to select "Specify (MB)" as 800 x 1024 = 819200 and select "Force operation" option.

After formatting is done, check tape slots properties, in Usage tab, it will show you 800Gb total capicity.
