Here is the associated text when putting the law in the existing Texas code (which as OP notes, this law is amending the existing Subchapter B, Chapter 43 where obscene has a legally defined definition for the subchapter in question). At least as written, it's another obscenity law, adding new penalties to a subset of content that already would be considered legally obscene under existing law.
Though that said, be it the existing obscenity law or this new obscenity law, prosecutors could obviously ignore the text of the law to push bullshit, as had previously happened in Texas with the Castillo case back in 2000.
