To reach into Tier 1 and higher levels of Tier 1 you need to prove that their is an qualitative difference, either one that is through comparing the lower level to some form of fiction compared to the higher level, or by the difference between levels being uncountably infinite.
Despite Elizhaa speaking of Reality-Ficiton relationships and deeper worlds being more "real", their is no such context in the quotes linked to. It's simply a matter of deeper objects being stronger and sturdier, not more real, based off the quotes presented.
The only other way the relationship of shallow and deep worlds would be relevant to Tier 1 is if the difference between the two is uncountably infinite, but the likes of world destroying magic not destroying a mundane ship, while impressive, is not the level of showcasing an uncountably infinite difference.
